Corrupted itunes match

after switching back from home sharing the itunes match on my account has corrupted and some of my albums songs are wrong I dont even know where they originate from. I also have some album covers which are not part of my collection. How can this be rectified?

The first file (unknown error) was corrupt at the point of initial iTunes match upload. I've re-ripped it from CD and the new version uploads and downloads to iCloud fine, but it is indicated as a duplicate of the corrupt track in iTunes, and I want to delete the old corrupt version from iCloud.
The second file (URL error) was fine before upload (again, ripped from CD). I retained a local copy and that works fine, however if I delete the local file (via iTunes), it won't redownload from iCloud, and nor can I simply paste the local version back into iTunes, because iTunes is convinced that the file only resides on iCloud and doesn't locate the local version.
This situation has been like this for some weeks now, I've just only now gotten round to mentioning it here.

Corrupted iTunes Match Uploads

So I have a couple of iTunes match uploads that seems somehow corrupted. I've removed the local files, but they won't re-download from iCloud. The two different errors I get are:
"An unknow error occurred (11111)"
and
"The URL "^0" could not be found on the server"
Most frustratingly, I cannot delete these tracks from iCloud either, the delete option is available, but hitting "Delete Songs" on the iCloud deletion confirmation dialog has no effect.
Any thoughts?

How can i report a corrupted itunes match song?

Several of the songs in my iTunes library matched successfully, but the tracks from iTunes Match are corrupted. So, they're fine on my iMac (ripped from my CD), but messed up on my mobile devices (downloaded from iCloud). I don't see a specific category in the Apple Feedback pages for iTunes or iCloud to report a botched song in their database. Anyone know the correct procedure to report this so Apple's team can replace their master copy with a fresh one?

Here's a similar thread:
https://discussions.apple.com/message/17184578#17184578
I did report this issue, but judging from the many posts on this, Apple hasn't paid any attention. Busy folks these days, I guess! For the most part, iTunes Match works very well. It's not a big deal to have a few tracks botched as long as you retain your original on your main system. It IS a big deal for people who are trying to upgrade their old original song files by trashing their main libraries and restoring from iTunes Match, because then you can't fall back to your old version when Apple's song file turns out corrupted! I posted a suggestion about that on the other link.
The more users bug Apple to setup a quick way to report specifically corrupted files found in either the iTunes Store or the iTunes Match database (not necessarily the same), the more likely they'll do something about it. Crowd-sourced Q/A for Apple!
And thanks for the link you posted, Michael=)

HT204406 How can I reset iTunes Match to my original version, before it was corrupted by iMatch?

How can I reset iTunes Match to my original version, before it was corrupted by iTunes Match? I have a extensive library I developed over years and it has been totally destroyed by iTunes Match and I have not been able to rectify it, no matter what.

Hallo Jim, thanks for the response.
I have a library of around 9000 songs, about 40 playlists and all albums sorted etc. It was originally kept on a Windows 7 based system. After linking the entire library on iTunes Matc (which took forever), all was fine for a while, then suddenly double playlists start apearing, songs disapeard form playlists and I started to loose all my settings!
In a last attempt to solve my problems, I purchased a Mac to use at home with all the other Apple devices. (Appletv, iPads etc) Unfortunatelly despite numerous attempts I have not been able to copy the library over to the MAC, as I keep on loosing half of the data. I tried iTunes Match, but this made things even worse.
Reading several forums and tutorials and trying everything, simply helped me to recover an older version of the Library by copieng a pervious version and replacing the current .itl file. (on the Windows based system)
So, I now have a fairly updated and complete iTunes Library on my Windows based computer at work, but all my other devices and MAC at home have skeleton versions of the original Library.
I have disabled iTune Match on all sytems as well as Genius , as this seams to be escalating the problems by creating multiple versions of my existing playlists, but none that are complete.
If you have advice for me, or can refer me to a detailed and accurate tutorial, I will be very grateful.
Thank you,
Hennie

ITunes match corrupt song downloads

Hi, I am not sure if anyone has noticed anything similar but like many I have recently used iTunes match to clean up my library and consolidate my songs ripped from CD's and/or downloaded from Amazon/Play.com etc into similar quality. In doing so I had about a 75% match rate and for these tracks I decided to download the higher bit rate versions from iTunes. While all appeared to download fine, many of the files appear to be corrupted in that they seem to stop half way through the song.
Now to fix this I have deleted the local file an re-downloaded a new copy (sometimes having to follow this process twice and even three times to get a working version). The only evidence that there seems to be something not right with the file is the file size is smaller but with having no basis for comparison the only way I have found to check the songs is buy playing through each one and skipping to the end of the track to see if there is anything there.
Has anyone else found a similar issue and if so, any easier way of scanning for corrupt song files? So far I have scanned 600 'matched' songs and found 30 errors. One CD which had almost half the songs with errors was Billy Idol's Charmed Life if anyone else has it and may want to check.

I would try one other test -- assuming you still have the original files, delete those 30 problematic files from iCloud, then import your original source files into the new library and then re-do the matching / delete local / download process again. In other words, now you're testing the entire process from start to finish with this new library, just to see the results. My guess is that you'll have the same problem, but at least this eliminates the library itself as a factor.
And assuming it's still a problem, then I'm not sure. I always figured that once the songs were Matched, they should be pristine at least on their end. but it's actually possible that these 30 tracks are in fact corrupt on the iTunes server end. I wish I had these songs to test, just to give you a 2nd tester to confirm if I saw the same issues. Other than that, if you had a different system or a different location you can test, you could at least eliminate hardware / OS as a factor.
And @carlton -- yeah, it was just a bad day yesterday. Going over the TOS I see what happened and how things were perceived. I just wish there was a way to give Apple more active feedback other than the feedback URL or chatting with an L1 rep. Hopefully they are reading this board and making notes.

Itunes Match tunes corrupted on Iphone 6 - deleting tune or redownloading doesn't fix.

I have several tunes I matched with itunes match from my mac. those play fine, if I delete and redownload from the cloud they play perfectly.
However, After getting my iphone 6 and recovering my backup, I went ahead and clicked on a lot of tunes / albums / artists to redownload to my phone from the cloud. I went to bed and all transfers but a few seemed to have downloaded. However, when I play some songs, they are corrupted... it will display the proper song's name, proper length, good album artwork, however the song will be only 20s short OR the song will start normally but after 10-20s it is another song that plays.
I have tried to delete the song and redownload. I have tried reboots, I am at the latest update version of IOS. I tried deleting and streaming from cloud... nothing changes, the song stays corrupted (as if cached this way)
Before I go with a clean restore + redownloading all in the hopes of clearing the cache, does anyone have any idea on how we can clean up the downloaded cache or ensure all works properly with itunes match?
Overall, I am a bit disapointed about this service... especially having to reclick all tunes to redownload everything instead of a sinple "sync" back to reality.... and then the corrupted tunes , bleh.

ever figure this out?

Recover lost deleted corrupted music files tracks from iTunes match icloud

Just spent an hour on Apple's tech suypport line, all to figure out how to recover lost/deleted/corrupted music files/tracks from iCloud / iTunes Match. Here's how to do it:
ASSUMPTIONS: You're in iTunes on your computer, logged into your iCloud account.
Within iTunes, in the left-hand pane, select your Music library. Alll your tracks should appear in the right-hand pane. Those that are missing from your disk should be marked with an asterisk icon to the left of the track. Do the following...
...select all the missing/lost/deleted tracks (using the option button), and hit the delete button.
NOTE: when the delete dialog box comes up, make sure you do ***NOT*** click the "Delete from iCloud" selection!!!
...once deleted, select all the same tracks again, then hit the right mouse button, then select "Download".
All the tracks should start downloading, one by one, from iCloud.
NOTE: If I were you, I'd perform this operation on discrete chunks (no more than 500 at a time), just to be safe.
Good luck!

You can also recover the missing tracks from the backup you are keeping on an external HDD. You are backing up, aren't you?

Library corruption on initial iTunes Match upload?

Has anyone else seen this behavior? I just subscribed to iTunes Match. It went through the whole parsing of the library and uploaded. But now the library is messed up - some movies were marked as music, music as movies, some song files appear to have been overwritten in the library (the Avengers movie actually replaced "Sing" by the Carpenters - it shows up listed as track 12 of 14, with a mix of entries from the movie and the original song). The original files appear to be untouched (thankfully), so I can probably rebuild the library without too much loss of data.
Is this a known "feature"? I think the convenience would be wonderful if the music didn't end up scrambled in translation...
Thanks for any feedback!

In iTunes turn off iTunes Match and quit iTunes. Then restore the iTunes Library.itl file from your backup that is from before you first turned on iTunes Match.

How to fix corrupted/partial songs in iTunes match?

Recently I dowloaded 5 new albums from soundcloud and added them to my iTunes library. Since I subscribe to iTunes match my mac started to upload the 'unmatched' files to the 'cloud' for access across my many devices. Once available I decided to play my newly acquired music. To my surprise every recently uploaded song only plays about 3/4 of the way and then skips to the next song.
I have done some preliminary research and I am at my wits' end. I have done the following per the suggestion of Apple and the many blogs out there.
-Delete all songs from my iOS devices and try to play the song again. - No Success
-Import the files into another library to verify the original are good. Everything sounds perfect.
-Delete the files from both my library and iCloud. Update iTunes match. Add the problem songs back into the library. Finally update iTunes match. - No Success
So.........how can i fix this?

There's a couple of way to do this.
Pull down View > Hide Music in the Cloud. This will effectively hide everything in the cloud and when you want to download more you'll have to show it again.
The other way is to use a Smart Playlist.
1. Pull down File > New > Smart Playlist.
2. Make the criteria something like Media Kind IS Music, Location IS on this computer. Click OK.
This will gather up all the tracks that are physically on the computer and you can play them from the playlist.

Playlist corruption on itunes match

Hi - I've just subscribed to itunes match and now my playlists on my iphone are all in the wrong order - i.e. upside down! Any ideas. The edit function only allows me to drag one track at a time and I have playlists of 50+ (english teaching cds). Thanks

Adding a Song to a playlist should certainly not remove it from the iCloud.
There are many reports of playlists being adjusted on iDevices causing issues, a common one being the replication of the playlist.
It would be helpful to answer the earlier questions if you can this will allow a clearer view and help identify the likely cause. The information needed can be found from the main Music view in your iTunes library - just add the fields to your standard view.
When you say 'how you are adding the Song to the playlist' it would be helpful to confirm if this is on your Computer or iDevice? It looks from your original post as though the issues are all apparent on the Computer iTunes client?

ITunes Match has deleted my music files. How and Why?

I have used iTunes Match since January 2012 however I have noticed that fewer and fewer of my songs are available on my linked devices (iPhone, iPad). When I go to the iTunes Media Library folder to see the original files, many are missing. Typically there are only 1 or 2 song files in an album folder and the rest are just not there.
On an IOS device the songs still appear in the playlists but if selected it will just jump down the list until it finds a song that it decides it can play.
My iTunes library folder was transferred on to a 2GB network attached Lacie drive as it was too big to put on my MBP Retina in July 2012. Currently I use a 2009 iMac for the main iTunes however it is still pointing to the iTunes folder on the Lacie. MBP and iMac are authorised with iTunes store and Home Sharing is on. MBP is set to use Home Sharing, so is not syncing with Match. Apple TV 2 can also access Match and Home Sharing.
To fix this I am now working my way through a backup from June 2012 and manually checking and synching my 1200 top level iTunes folders. Honestly most album folders have only 1 or 2 tracks so I am copying back all the missing tracks one folder at a time. (iTunes has 14000 songs). I cannot merely replace the corrupt new library with the old library backup as the last 12 mths of acquisitions would disappear.
Further there are tracks that have been renamed and filed incorrectly. I have tracks labelled as Bowie or Daft Punk, in Bowie or Daft Punk playlists that are actually from an album of recordings of bird and animal sounds from sub tropical tropical rainforests. Now that kills the party when Harder, Better, Faster, Stronger crossfades into the sound of the mating call of the green tree frog let me tell you.
I have rematched my library several times over the last 12 months. When moving to the Lacie and MBP, then again when moving to the iMac for iTunes but leaving the files on the Lacie.
It's a big mess that will take me about 12-15 hours of filing to (mostly) fix. I'm up to "J".
Why and how did my original files disappear off my Lacie drive? This software/service should not have those rights.
I am a Mac fan and a college IT Teacher so run a well organised home network and am just at a loss.
Please advise.
MBP Retina 256GB 16GB 10.8.4, iMac 21" 2009 500GB 4GB 10.8.4, iPhone 4s 32GB 6.1.3, iPad2 32GB 6.1.3

iTunes Match does not have the ability to remove local files.
The service operates by comparing the selected iTunes Library with the iTunes Store content and 'matching' or 'uploading' - it is very straightforward a 'match' provides equivalent access to iTunes Store content as a recognised 'purchase'; upload simply copies a 256k AAC variant into the cloud. There are no elements of this activity that can erase the local library content.
Would suggest you explore possible alternative causes of file loss. Given the pattern described of selective deletion, leaving many Songs intact - would suggest making at least 2 secure offline Song file backups and starting the library again from a fresh install of iTunes once a thorough sweep of the system has been completed for virus. It is also worth assessing the physical security of the system - who has access & with what privileges.
To access Songs from the cloud, you would have to manually delete the Song from the library or open an empty library - so even when accessing content, iTunes Match provides no local deletion capability.

PLEASE HELP -- iTunes Match - multiple problems, desktop and iOS

I've been going round and around with this issue for the past couple days (yes, I've been dedicating that much time to it) and finally went to the Genius Bar today to get help and even they were stumped. Hoping someone here can shed some light on the situation. Next stop, express lane for support.
Broad Problem:
I paid for iTunes Match around 6 months ago and activated it on my desktop.     Since then, I've had nothing but problems across my desktop and 4 seperate iOS devices (3 iPhone 4's, and an iPad 3). The basic sympton on the desktop is that iTunes itself frequently freezes (Option-Command-Esc reveals "Application Not Responding") and requires a force quit.   As soon as I turn OFF iTunes Match, this symptom goes away. I can leave iTunes open for hours without any problems. As soon as I turn it back ON, then the problem comes back -- sometimes iTunes won't launch at all (crashes before bringing the UI up), and other times it's the same freeze that requires a force-quite. Quite frustrating.
On the iOS side of things, the situation isn't any better.   When I toggle on iTunes Match and then enable "Show All Music" in the Preferences of the iPhone, then I get any one of the two following scenarios:
A) The Music App simply won't load. It tries, goes to white, and crashes back to the home screen of my iPhone.
B) If I'm lucky, the Music app will launch and I can see my entire library in the cloud as intended. The problems start though when I go to actually download/play songs from the cloud. Typically, the songs will start playing but I will eventually get an error message that alerts me that there was "Problem Downloading Track". When I then go into the Download Que of the iTunes Store (again, still on the iPhone), it shows the entire list of songs that I had wanted to download and shows them at various stages of download completion -- even if they have actually completely played on the phone itself.   Sometimes they will time out and display the "problem downloading track/try again" status, and other times the progress bar sits at about 99% with a status of "Processing".
What's particularly strange about scenario B is that I've tried to download a variety of songs to different devices -- my wifes iPhone 4, my iPhone 4, an iPad, and a iPhone 4S that the person at the Genius Bar had me use as a tester.   When I tried the iPhone 4S at the genius bar, I was amazed at how fast it downloaded to the device. This had the genius bar guy wondering if it was a problem with my phone itself or with the iPhone 4 in particular.   Unfortunately he didn't have a spare iPhone 4 to test with so I had to go home and test with my wife's iPhone 4. Again, she had the same problem.   The status bar hangs at about 99% showing a status of "processing", even though I have completely listened to the track within the Music App. The same scenario happens on the iPad as well.
Okay, if you're with me so far: here's where things start to get REALLY strange....
On MY iPhone 4, when I run into problem A or B, the only fixable solution for me has been to go into Preferences and toggle OFF iTunes Match, completely shut down the phone, restart the phone, and then launch the Music App, at which point I can see the music that has loaded to my phone.    The kicker here is that even though I've turned iTunes Match OFF and completely powered down my phone, when I go into the Music app I can ALSO see my ENTIRE iTunes Match library, completely with cloud status icons.   It's as though I never turned off iTunes Match at all. In fact, I had to triple check my own preferences to verify that it was turned OFF, which it sure enough is.   I can even go and attempt to download songs, with various levels of success based on the problems above.
Now, on my WIFE's iPhone 4, when I run into problem A or B, I tried the same process in tandem with the phones side by side as I did the test -- turn iTunes Match OFF in Preferences, power down the phone, power up the phone, and launch the Music app.    However, on her phone, when this happens the Music App shows what is to be expected -- only the music that is on the phone itself.
Okay, there's a lot to digest here, but here's the synopsis: my phone and my wifes phones are behaving differently when displaying iTunes Match, with my phone appearing to completely disregard the status of the On/Off Toggle within Preferences-->Music, and my wifes phone behaving as it should, at least in terms of what it displays.   The download problems are present on each device and the iPad is also behaving like my wifes phone.
Given all of these inconsistencies and irregularities across devices and platforms -- MacBook Pro running Lion, separate iPhone 4's each running iOS 5.1.1, an iPad running iOS 5.1.1. and an iPhone 4S running iOS 5.1.1 - my suspicion is that:
A) I've got a corrupt iTunes library file residing in the cloud
or
B) iTunes Match is having a hard time reconciling my Apple ID across so many devices (possibly complicated by issue A)
The bottom line is that I have paid for iTunes Match and have never been able to use it successfully or with any predictability.
I'm wondering if anyone else has any symptoms that match any of this and/or have come across a corrupted file in the cloud and, if so, how to remedy the situation. Since it's in the cloud, I can't do anything about. I can't even see it. Most troubling.
Note:
When I went to the Genius Bar, they had me do a complete restore of the phone (not from backup) to elminate any corrupt files within the phone itself. Even that didn't solve the problem.   That's when he brought out the 4S phone to test on and we were both so shocked at how blazingly fast the songs downloaded, error-free. That phone was able to download 8 songs completely before one song downloaded to my phone sitting right next to it. Both on the same Apple Store network and both downloading the exact same tracks using my Apple ID and login.   While it's tempting to say that the 4S is faster than the 4, I don't think it's 8 times faster with download speeds over WiFi.   However, even if the speed/completion discrepancy is because the 4S is superior, it doesn't explain the mind-boggling disparity between my wife's phone and my phone -- both iPhone 4's and both running the same iOS.   Throw in the oddity of iTunes on Lion crashing whenever iTunes Match is on and this all seems to point to some corruption in the cloud that perhaps the 4S device is able to bypass...for whatever reason.
Please help. This is nuts.

Exactly same problem - any ideas - I get error message 14

I've twice tried to use iTunes match. It stalls in step 2. I've rebooted my Mac computer and still stalls. Apple's taken the $25 but not delivered the service. Can I get some personal help?

I've twice tried to use iTunes match. It stalls in step 2. I've rebooted my iMac computer and it still stalls. Apple's taken the $25 but not delivered the service. Can I get some personal help? There are 12,733 songs, a few dozen of which are not going to be in the Apple music library because they are unique to my collection. Also, some titled "Track XX" and no artist. I assume these would either not upload or else just be uploaded. But, after an overnight of step 2, the iTunes match program was still on song number 7384 or 12733 (it was on that number for over 12 hours). Looking in the music library, activating the iCloud icon and status fields, there were hundreds of songs with the status "waiting."

After taking my late 2009 15 inch macbook pro to the apple store, the genius completely erased my computer and reinstalled the Mac OS X software, but the problem still persists.
I also took it to my college tech support center, they tried to take the ram out and reinsert it and clean up the dust, but the problem still remains.
I am able to use my computer in Safeboot mode (only)
Well it could still be a software problem if you installed a third party program after the OS X wipe and install, because by booting into Safe Mode it disables certain functions of OS X and hardware. Check for updates or problems for all your third party software, include everything, including menulets, System Preference panes, hacks and so forth.
If you restored any sort of software from backup like TimeMachine, it likely was corrupted data and now is returned.
If the college tech support found a lot of dust clogging the rear exhaust vents behind the fans, then likely the heat damage done to the machine has already occured and can't be reversed. Video cards are usually first to go, which Safe Mode does disable the video card somewhat.
Run through this list of fixes, it's systematic in nature, also has a Hardware Test to see what's going on

Too bad this is occurring to a mere 4 year old machine, but dust will do that. Here is the culprit that Apple doesn't tell anyone about.

ITunes Match keeps repeating and Sonos Play 5!

So this note has two pieces to it, one related to iTunes Match and the other is Sonos Play 5. First an observation about the iTunes Match repeating problem. I wanted to start using iTunes Match for a couple of reasons so I started to run it. It went through Step 1 and Step 2, started Step 3, stopped and restarted on Step 1.
So I was reading trying to find a solution in the Apple Support Community. Some suggested that there was a corrupted song in the library so I went back to watch to see if I could catch when it left Step 3 to go back to Step 1. I was not really able to see exactly were it was reverting back to Step 1.
I then discovered ajlewis1851 note about reset Match, Store and the computer (https://discussions.apple.com/message/20530276#20530276)
I also discovered a song that was not in my library so I deleted that from the library as well. Neither of these seemed to work and it was back repeating itself.
I left Match running while I was doing more searching and I discovered the thread about gating the upload speed as the upload speed might be the problem. Well I spent a long time trying to figure out how to slow my Airport Extreme Base Station down and then I noticed that Match was uploading between 2-15 files before it would kick back to the beginning and the total number of files to be uploaded was slowly decreasing.
Low and behold after quite some time, Match finally finished and said it was done! This has to be some serious bug in Match, but eventually it got done. Not sure whether the two steps before helped or not.
Now to the beginning of the story. I started down this path because I was setting up a new iPod Touch to serve as controller for my new Sonos Play 5 system. Everything seemed to work fine with Pandora and I was very excited. Synced a few playlist from my iTunes library and for many of the songs there was the dreaded ‘unplayable icon”-circle with a line through it! Did some additional searching and discovered that the iPod Touch to Sonos Play 5 was only possible with DRM songs.
This is an aside. It is necessary to place this discovery against my experience of playing my iPod thru a Sonos iPod Dock without having to worry about the DRM status of the music. My disappointment was nearly overwhelming.
But Sonos recommended a strategy of iTunes Match to remove the DRM from the songs in my library. Hence, my need for iTunes Match from the beginning of this story. But this is not a very clean solution. Even after one has done the iTunes Match, it is necessary to find all of the ‘Protected AAC audio files’ in your library, delete them and then download the ‘Purchased AAC audio files’ from the cloud. (https://sonos.custhelp.com/app/answers/detail/a_id/626) and Apples directions (http://support.apple.com/kb/ht1711)
There are of tricks in doing this ‘Protected’ to ‘Purchased’ transition. When you select Music in your library, and then right click on the top bar above the music you can select additional columns to be shown. Select ‘Kind’ and you can see which music is protected vs purchased. You can sort this column, thus bring all of the ‘Protected’ files together, select them all and with one right click delete them! (I very very strongly recommended you have a couple of backups of your library, just in case and there is a small box in the dialogue about deleting them from the Cloud as well---MAKE SURE THIS BOX IS NOT SELECTED). Much to my delight, in the ‘Cloud’ column, you are presented with the choice to download the ‘Cloud’ version (now DRM free). As best as I can tell, one has to download each song from the Cloud individually. My fingers were very tired after millions of clicks. I did a few at a time so it took me the better part of a day to accomplish.
I was very excited because I now had DRM free music in my library (I figured this would solve the problem). I connected the iPod Touch to the library, choose not to sync my playlist so all the playlists from the iPod Touch were removed and then reselected the playlists of interest and had them placed back on the iPod. I ejected the iPod and tested the playlist on the Sonos. Much to my surprise, the unplayable songs were still unplayable!!!
I deleted the Sonos App and reinstalled it (Did not work).
I deleted the playlist from the iPod Touch, and resync it to my library (You really don’t want to do this as it also deleted the playlist from my library!) Fortunately, I had one of those backups.
I then sync another playlist to the iPod Touch. This second playlist was the complete album from which two songs were placed in the original problem playlist. Much to my surprise, all of the songs from the album were fine, EXCEPT, the two songs that were unplayable in the original playlist.
I finally came to the conclusion that something had been stored on the iPod during the initial sync with the DRM containing music that prevented the non-DRM music from working properly. With a deep breath, and only after I disable the iPod Touch connection to iCloud (in a couple different places), I then went to Settings > General > Reset > Erase All Content and Settings and ran it to restore original factory settings. It was plugged into a power source.
After setting the iPod Touch up again, I reconnected it to my iTunes library and moved the problem playlist over that contained several unplayable songs. IT WORKED! All the songs were playable.
LESSONS:
1. If iTunes Match keeps repeating steps 1 and 2 watch carefully to see if the number of songs to be processed is changing for the better. If yes, at least in my situation, it completed the process, but it took much longer than I believe it should have.
2. My suspicion is that if you have installed DRM protected songs on an iPod Touch, the Sonos recommended solution will not work as stated. Interestingly, it did seem work on my iPad and 4G iPhone.
Addendum: I have discovered a few songs where the Sonos recommended solution did not work on the iPad and iPhone as well. Several are from the Madonna.

Well.....It is now working....... Including converting locked tracks located on the IPad library into unlocked 256kbps tracks playable by Sonos...
Used these steps:
Signed up for ITunes Match using ITunes on a Windows PC
Let Match do it's thing with 700 or so tracks
Followed the procedure in the link above to create a smart playlist of tracks with bit rates less than 256kbps
Using the smart playlist as a guide, I deleted or download tracks not appearing in Sonos on the PC. Then, refreshed the Sonos music library and confirmed these tracks now available and playable by Sonos
On the IPad, for tracks that were grayed out in Sonos, I deleted and re-downloaded the tracks using the Music app (swipe right to left on a track to delete it)... then got into Sonos on the IPad to confirm the tracks no longer grayed out.
So... I'm now happy.... I like the Sono system of WIFI streaming which is very flexible and produces decent sound quality, but did not realize until after buying the Sonos bridge and two Sonos speakers that older ITunes songs would not play in Sonos due to DRM locking. So, will now work through the library of locked tracks converting and re-downloading.
Thanks again for the pointers on this question.

Itunes match deletes random songs from my iphone, even if i re download them from the cloud, the next day another 3 or 4 are deleted by itself, anyone know a fix?

anybody know how i can fix this, i already tried to turn off itunes match off and on again on the iphone but it does not seem to work, also artwork once downloaded into the iphone it does not stay there, the next day its just a blank artwork and after the internet circles in the top left of the iphone stop spinning, i go back to my music library and then back to the song and it downloads it, but it does not stay there forever, any fix?
it would be kindly appreciated since this is a very annoying bug, specially the songs that just get erased from my iphone for no reason.

Hi Kevinpnb,
Welcome to the Support Communities!
Sorry to hear of your frustration with Music Match on your iPhone. You should be able to delete the music from your iPhone by following the steps in this article:
iTunes Match on iPhone, iPad, or iPod touch
http://support.apple.com/kb/HT5637
Deleting songs downloaded to your device
You can delete a song or album from your iPhone, iPad, or iPod touch at any time. Don't worry; it'll still be in the cloud.
Tap the Music app.
Tap More > Songs at the bottom.
Scroll or search for the song you would like to delete from your device.
Swipe right to left on the song, and then tap Delete.
Note: You must be in Artists, Songs, or Albums view to delete songs from your device. Deleting from a playlist won't remove a song from your iOS device.
Also, this information can be found on page 64 of the iPhone User Guide for iOS 7
http://manuals.info.apple.com/MANUALS/1000/MA1565/en_US/iphone_user_guide.pdf
Remove a song from iPhone. Tap Songs, swipe the song, then tap Delete. The song is deleted from iPhone, but not from your iTunes library on your Mac or PC, or from iCloud.
If you have iOS 7, this will delete the song from local storage, but the song will still appear with a cloud symbol in the Music app, as you've noticed. To hide the iTunes in the Cloud purchases, navigate to Settings > iTunes & App Store, and disable "Show All: Music”
There may be a few orphaned songs on your iPhone that were partially downloaded or corrupted in some way. If that is the case, you can erase all of the music from your phone. Follow the instructions below and select the Music app under Usage:
iPhone, iPad, and iPod: Understanding capacity
http://support.apple.com/kb/ht1867
If the issue still persists, try backing up your iPhone to iCloud, and then restore it:
iCloud: Restore your iOS device from iCloud

I hope this information helps ....
