ITunes ID3 tags handling for artwork

I have created MP3 versions of my band's artwork for inclusion in an online radio.  I am running into some issues with ID3 tags.    The MP3s show the artwork and everything just fine on my Mac.  However the artwork doesn't show up in the radio software (Centova) when the files are uploaded.  Because of this, I've got a crash course in ID3 tags--at least the album artwork tags.
It turns out, in ID3 tags version 2, there are no less than 15 different ID3 tags reserved for artwork--meaning you can attach up to 15 separate pieces of artwork (in theory) to each MP3 file.  Here are the tag reservations:
$00     Other
$01     32x32 pixels 'file icon' (PNG only)
$02     Other file icon
$03     Cover (front)
$04     Cover (back)
$05     Leaflet page
$06     Media (e.g. label side of CD)
$07     Lead artist/lead performer/soloist
$08     Artist/performer
$09     Conductor
$0A     Band/Orchestra
$0B     Composer
$0C     Lyricist/text writer
$0D     Recording Location
$0E     During recording
$0F     During performance
$10     Movie/video screen capture
$11     A bright coloured fish
$12     Illustration
$13     Band/artist logotype
$14     Publisher/Studio logotype
Yes, you read that right, there's a tag for "A bright colored fish".  So here's the rub:  I'm finding that iTunes defaults album artowrk to the first position (00), which has a certain logic to it.  But, I'm finding that this radio software, and some other pro level software looks for cover art in the third tag (Cover Art) be default.  This makes a number of problems.  It means that I'm having to find a serious ID3 tag editor to change the iTunes artowork tag from "00-Other" to "03-Cover Art" in order for it to be properly displayed.
NOW THE QUESTION:  Does iTunes have any sort of method to select which "type" of cover atwork tag you want to apply to the added artwork?  Or am I at the mercy of iTunes' default designation and that's that?

Apple have this help, which I guess you will have seen:

  • ITunes, ID3 Tags, and Metadata

    Oh hai der!
    I'm new and I'm so sorry if this questioned has been answered before. But I've done some research on the web and I've got some questions about iTunes and what it does to my music.
    First, here's my situation. I love iTunes, it's awesome, helps me edit my library beautifully. But that's only when all the songs, movies, videos, and so on have their information. Otherwise it's a huge mess. Which is what I'm dealing with.
    I like to use XBMC. I own a Samsung Galaxy S2, and an iPod Touch. The files I've edited and whose data I've put in manually, show up wonderfully on my iPod. But not my Samsung and media library software, or other device. I was wondering if iTunes actually edits the metadata and ID3 tags of the actual file in my computer. Not just in the iTunes program. See, let's say I have a song titled "Track 01 ", and in iTunes I change the name of the track to "Yesterday". Will iTunes actually edit the title of the song WITHIN the file itself? Or just in iTunes itself? So that after I edit the title within iTunes, it shows up in other software, such as XBMC, and devices like my Galaxy S2 as "Yesterday" and not "Track 01"?
    I don't get my music from iTunes. I've only got a few albums from iTunes, that's it. But for the rest, they're not from iTunes. It may not sound like a lot to most of you. But I've got a library that's over 50GB's large in music. That's over 8,000 songs. Only about 1,000 of those songs have their data such as lyrics, artwork, artist, album,  and so on. But for the rest of the 7,000 songs, it's just a mess. I've looked up many programs that edit my library for me. But I'm in a situation where I can't spend much money. So I'm looking for freeware. But that's not all.
    I'm looking for a piece of software that'll implement lyrics, artwork, album, artist, etc, into the song file itself. Or just in iTunes? I know of TuneUp, and Rinse My Music. I was wondering if there was other software out there? I've also heard of Beets, but it seems way too complicated for me to install properly.
    So to summarize, what I want to know is:
    1) Is there some freeware out there that'll help me edit my iTunes library?
    2) Does editing song info within iTunes actually do anything to the song file itself?
    3) Will I have to use some other software that organizes my media and actually edits a file's properties to display proper data?

  • Itunes, ID3 tags, & hard drive corruption

    My wife is having a strange problem with her iMac, and it’s got me a bit mystified. I’m hoping someone here can shed some light on what might be going on. I apologize in advance for the long post.
    The problem is that when she plays some songs in iTunes, and entirely different (wrong) song plays instead. Most songs play fine, but some just play entirely different songs (or sections of a song or podcast). All of the tracks are MP3 (either 192 kbps or 256 kbps) and almost all of them were encoded using Windows Media Player on an XP machine. Initially, I copied the music over from an NTFS drive to a newly formatted (Mac OS/HFS+) drive on the Mac, then I ran iTunes and created the library. At that point, everything seemed fine. All the meta data (song title, album title, artist, album artist, genre, album art) showed up in iTunes, and everything played correctly.
    Now we’re getting this weird behavior where we play some songs and get the wrong music. At first I thought the iTunes library files (ITL and/or XML) had been corrupted, but it seems on closer inspection that the entire hard drive has been corrupted. When I look at the files on Mac hard drive via the Finder, all seems ok – the directory structure is intact, the file names and sizes are all correct, and a Get Info on any MP3 file shows that the ID3 data is all there and seems accurate. This is true even for the songs that play wrong, but if I play one of those songs using the little mini player in the Get Info dialog, the wrong song plays (the same wrong song as in iTunes). So now I’m getting the behavior straight off the drive, with iTunes closed and the iTunes library completely out of the equation.
    Some other interesting clues/evidence:
    * This has happened before. When her first hard drive got corrupted (in the same way), I was mystified but chalked it up as a bad hard drive and got her a new one. Then we started over with a clean HFS+ formatted drive and clean music files and built a new iTunes library. And now the same thing has happened again. So I don’t think it’s just a bad hard drive.
    * It seems to be progressive. That is, everything was fine in the beginning, but over time more and more files get messed up. We know this because we have a backup that’s about a month old on which we can locate files that are fine (on the backup) but that are messed up on her connected day-to-day drive. So it seems like some activity on the drive is causing problems that are growing over time.
    * There is some weird meta data (ID3) behavior. I copied a few hundred MP3 files from the Mac drive back to the PC (over our home network) and looked at them in the Windows Explorer. The first thing I saw was that the same (wrong) music played for the bad tracks as had on the Mac. And I also saw that a lot of ID3 tags were not showing on the Windows side. Lots of tracks have no ID3 data (album, artist, genre, etc. is missing) when I look at them on the PC. There are many albums where tags show up correctly for some of the tracks but not for others. In fact, the number of files where the ID3 tags aren’t visible on the PC far exceeds the number of songs that play incorrectly on the Mac. When I look back on the Mac at the songs that have no ID3 data on the PC and do a Get Info, I see the ID3 data.
    * Often, though I can’t say always for sure, the wrong music that plays on the Mac is stuff that has been recently added. Either podcasts or music that my wife has added since the initial library was established.
    My best guess (though still full of holes):
    Something is confusing the Mac OS into writing on top of occupied space on the hard drive or into mapping files incorrectly in the drive’s allocation table, and chaos results. The Mac doesn’t think anything is wrong, and it shows everything as being clean in the Finder. So I started thinking about the kind of reads & writes my wife is doing on that drive. She rips new CDs to add to the library, she downloads new Podcasts and deletes old ones, and she changes ID3 tags.
    I’m focusing on the changing ID3 tag activity. My wife doesn’t like the way I tag genre. I like big broad categories, an she likes smaller, more specific categories. So she has gone through the initial library of 42K+ songs and changed the genre on thousands of songs. She’s change some from Pop to Power Pop or from Pop to Indie Pop or from Rock to Indie Rock, etc. Both WMP (where the tags were created) and iTunes support ID3v2.3, and so these two programs ought to be able to change tags in a totally interchangeable and safe way. But what if iTunes writes its new genre tags in a way that’s slightly different from WMP? Could iTunes be writing to memory/disk locations that are outside the boundaries of the file and thus creating some kind of buffer overrun?
    It really doesn’t make a lot of sense, but it does tie back to the evidence that this has something to do with meta data, gets worse over time, happened on more than one disk, and seems to be a file allocation table issue.
    Even if I get to the bottom of this, I think my wife’s HD is toast for sure. Here’s what I think I will do: I’ll reformat the drive, re-copy the music over from the PC, and build a new iTunes library. Then, first thing, I’ll open iTunes, select all the songs in the new library, and run “Convert ID3 Tags” to ID3v2.4. If that works and everything behaves correctly, I’ll try to change some genre tags and test the results. The problem is that the library is so large that problems can go undetected for a long time, so maybe I should do this first with a small subset of the music as a trial run.
    The thing I want to avoid is having to do this (ever) again, so I’d feel more comfortable if I understood the bug/problem before just following this guess (which feels like a roll of the dice). If anyone has seem similar behavior or has heard of any IDS incompatibilities between WMP 11 and iTunes 7, I’d love to hear about it. Any help is appreciated.

    Wow, that was a long and detailed post. I haven't the energy to reply in equal fervor, but I will just say that lately these boards have been peppered with posts from people whose MP3s are being eaten alive by iTunes. What I don't get is why you suspect the hard drive is at fault. Unless the rest of the system is caving in, I don't think there's any reason to suspect a failing drive. Check the S.M.A.R.T. status in Disk Utility if you haven't already, and perform whatever maintenance you believe is in order.
    For the most reliable ID3 tag editing, I'd certainly recommend using foobar2000 on a Windows PC (or a Mac with Windows installed) or MP3Tag. I would definitely, at least for the time being, not put your huge music collection at risk by doing any further editing of the tags in iTunes.

  • ITunes + ID3 tags..

    Hey guys its my first post here
    I don't really have a problem relating to connectivity or anything major. But I do have a question.
    When I drag and drop songs into my playlists in iTunes 6.01, I later re-edit the artsists name and album to my liking and have it shown exactly how it is on my iPod Nano. But the problem is the ID3 tags on the actual MP3 is also changed at the same time. Is there anyway to have iTunes not touch the ID3 tags on the mp3 itself after editing it thru iTunes?
    I currently like the way I have the artists and album names all sorted out, but I just found out, it also edited my actual mp3 files, and thats not really good for me because I have the mp3 files according to an sfv file which checks CRC's..
    any help is appreciated guys.

    Is there anyway to have iTunes not touch the ID3 tags
    on the mp3 itself after editing it thru iTunes?
    No. When you edit the song info in iTunes, you are editing the file tags. That is a tag editor, not just a "iTunes Information" editor.
    I currently like the way I have the artists and album
    names all sorted out, but I just found out, it also

    If you don't want to change the tags, then don't use the tag editor to change the tags.

  • AppleScript for changing ID3 tags

    I have around 200 songs in my iTunes library that are marked as Podcasts that I've been trying to get to show up in the Music section with my other songs. From what I've heard, Podcasts are marked with a special extended ID3 tag that can't be easily removed, and the only way to get rid of it is to just strip all of the ID3 tags from the song completely. The thing is, I don't want to write down the song title, artist, and album name of all 200-something songs and then enter them in again manually. Is there a way I can write an AppleScript that will keep the ID3 tags of a song in memory or save them to a text file, strip them from the song, then re-enter just the Title, Artist and Album tags (preferably one that will do that for every song in a specific folder)?

    I looked at the apple script dictionary and there is no ID3 tag listed for itunes tracks. There is a podcast property of tracks which is "true" for podcasts and "false" for everything else. However, this property is read only and thus can not be changed by an apple script.

  • ITunes Match Sync Erases ID3 Tags

    I have had no problems with the iTunes Match syncing between the iTunes that was on my PC (version, I don't know, but it was older than 11.4) and my iPhone and iPad.
    But today I upgraded iTunes to the latest and greatest version (11.4), and now everything is MESSED UP. When I connect this new iTunes to my iTunes Match account, now all of a sudden all of the playlists on both my iPhone and iPad got messed up and came out of the Playlist Folders they were in and are now top-tier playlists. When I try to move them back into their appropriate folders in iTunes and re-sync, the re-sync effectively erases from iTunes the changes I just made. For example, it puts the playlist right back to where I moved it FROM. If I try to create new playlists, the sync erases them from iTunes. Even if I try to update an individual song's ID3 tag (like, for example, if I add some text to the "Grouping" field of a single song) and re-sync, the updated text disappears and reverts back to what it was before I synced. I don't even have my iPhone or iPad connected by cable to the computer, so it's not like iTunes is getting confused between whether to sync via cord or via iTunes Match.
    I don't know what to do. Is my iTunes update corrupted? It seems to be functioning fine otherwise. No alerts. No bad DLLs. Nothing weird other than the iTunes Match syncing problem.
    Any suggestions?
    Thanks.

    You should check with the head unit manufacturer; they can most likely answer your question.

  • Itunes is messing up ID3 tags and song info.

    I am wondering, why is itunes keeps on changing ID3 tags.
    For example. All my "The Thunderlords" songs have been changed to"thunderlords,the" Which I do not like. AC/DC got changed to DC/ac and the art was gone. Random comment such as "0" have been added to nearly every song. The album "The Wall" has been labled as "Wall, The" I do not like this >_> is THE wall not wall the. What the .... is wall the? It's not like I go around says "what heck the?" or "halo above his head the" I'm not Yoda! I'd just like to know how to stop itunes from editing this without my permission.
    All songs are MP3's. Details:
    96 kpbs (mono)/ 192 kpbs (Stereo), Normal Stereo, optimized for MMX/SSE, using MP

    Welcome to the world of Gracenotes. This is the database that Itunes reads to name your files. Apple pays a royalty to these clowns and this is what you get; misspellings and just plain wrong info.
    I constantly sort and edit my 1300 CD collection so I would suggest you learn to do the same within iTunes. If the author names are reversed, fix one then copy. Itunes will let you select and change multiple fields once you learn to do multiple selection..not hard but tedious at times.
    Apple needs to threaten to let us use the free CDDB for an alternate look up and a swap button on authors names, and so forth..

  • ID3 tag incompatibility between iTunes and other media jukeboxes?

    Hi
    Although it is very nice, I feel iTunes lacks features in regards to smart id3 tag management for large libraries. I bought Music Match because of its capabilities to mass-change of tags and auto-completion of information using filenames and/or the Internet.
    Besides the fact that Music Match does not recognize the nano, now in many of the songs whose tags have been corrected using Music Match (same for RealPlayer) will appear corrupted for iTunes: they will not play, if transferred to iPod, will not play there either, and if removed from itunes and then reinserted, the songs will not even reappear in the main library list. That is, the songs are lost as far as itunes is concerned, even though I can still play them with any other player (winamp, music match and real player).
    So maybe itunes converts the tags to some format only itself will understand? And itunes would do this only once, at first, so that if the user externally changes the tags, something bad might happen? Any past experiences on this?
    Any help will be appreciated.

  • ID3 tags for non-purchased TV shows

    I think Apple's approach to ID3 tags for purchased TV shows is perfect. You can browse by the show name, select the one you want (ie. Lost vs Desperate Housewives), then the specific episode names appear on the next iPod screen.
    However, all of the ID3 tags used for purchased shows are not available for shows downloaded through bittorrent or recorded with EyeTV. This means we can't use tags for "Season", "Episode #" and "Show". I think they would work if only we could declare the "Video Kind: TV Show", but this option is grayed out in the file's "Get Info" options tab.
    This severely impacts browsing for videos on the iPod. Currently I have to name my videos something like this "CSI: Season 6: Episode 1: Bodies in Motion" in order to browse effectively for the file on my iPod. I'd love to name it simply "Bodies in Motion" -- WITHIN the "Season 6" folder -- WITHIN the "CSI" folder. [I'm not using "folder" literally -- I'm just trying to imply a hierarchical structure.] Without these tags, this "foldered" browsing isn't possible.
    Anybody figured out how to get around this obstacle?

    I downloaded a TV Show and three music videos and the music videos are on my Ipod but the TV show is not and there is no category for TV only for movies and suggestions

  • How do you display ID3 tag info?

    Does anyone know how to display detailed id3 tag info for a song that is playing? I'm looking for a display of the bitrate, genre, file size, track number, etc. I've tried pressing the center button a few times as suggested by the manual, but it doesn't do anything but change the progress bar.

    Thanks. I didn't think it was possible to see the extra ID3 tag info, but it doesn't hurt to check since I'm new to iPod.
    My old archos jukebox allowed ANY id3 tag info to be displayed and in any manner I chose. I'll miss that.
    However, the album art display is nice, which the archos doesn't have.

  • Writing tag in a tag handler

    Hi,
    I was wondering if it was possible to embed tags in the output of a tag handler.
    for example, depending on an attribute, I would like my custom tag <MyTag/> to write out a <fmt:message/> tag. I tried something like pageContext.getOut().write("<fmt:message key='mykey'/>"), which writes out the message tag, but it doesn't get evaluated because the body content is evaluated already. So all I see is the tag <fmt:message/> instead of the actual message.
    Is there a way to re-evaluate the tags in the body after the tag handler has a chance to write something to it first?
    Thanks.

    No, there isn't.
    The best you can do is write a tag handler using a .tag file.
    .tag files are to Tag libraries what JSPs are to Servlets.
    So you write you custom tag potentially using other custom tags in the process) it then translates that tag into java code.

  • How do I add album artwork to iTunes, but NOT to the ID3 tag, manually?

    I imported a lot of mp3s into iTunes. After some messing about with ID3 tags, I got iTunes to download most of the Artwork for my albums.
    I've found a lot of the other covers using Slothradio, and I started to copy the images into iTunes. However, I noticed that it was actually adding the images into the ID3tags.
    When I checked the music for which iTunes downloaded the covers, it DIDN'T put the artwork into the tags.
    So, how do I add the covers to iTunes like it does itself, without putting them in the ID3 tags?
    Any help appreciated.

  • ITunes is randomly deleting ID3 tags track number data and album artwork

    A few weeks ago iTunes 10.5.3.3 starting deleting the amount of tracks available for an album and its artwork when I would play a song. Thus "4 of 12" would go to just "4". And in some cases the artwork I've had for years and years (since iTunes 6) is disappearing for an entire album when only one song is played as well. There is no pattern or any discernable reasoning of what tracks its choosing to do this with. It's really disheartening when you factor in all the time and effort involved  for nearly 10 years with making all of that data correct and adding customized artwork for 10,000+ songs for it to now just start disappearing randomly.
    I suspect my iTunes database file is corrupt, however, how do you fix that without losing all of your Playlists, Artwork, etc.?
    I've loved and had zero problems with this software until a few weeks ago. I'm a happy owner of multiple iPods for all this time and now this is disconcerting.

    The missing total track count numbers strongly points to Windows Media Player. It has a nasty habit of "refreshing" the metadata when you didn't ask it to. This can happen even if you don't use the program as a rule as it may be launched in the background when viewing certain media content on the web. Next time iTunes has a reason to inspect the tag, e.g. during playback, it will reveal the new data from the tag. In essense the damages is already done but iTunes has yet to notice all of it.
    For tips on getting WMP and iTunes to play nicely in future see this thread.

  • My iTunes library and metadata/ID3 tags issue

    Since 2010, iTunes is the only media player I use to play music. My library consists of music purchased from the iTunes Store, CD rips and stuff many artists these days release as freebies on the internet to promote a new album. Also, M4A and MP3 are the only formats I use so far.
    Since iTunes, I really got into editing my library's metadata tags by hand, in order to create a custom archive which serves my preferences best. I should mention that besides iTunes being the only software I use to play my music library, it's also the only software I use to edit their metadata. Also, before iTunes – when my library was on different media players – I never bothered with editing them.
    A few days ago, I found how a lot of people in forums complain about the way iTunes edits and stores metadata. So, I experimented and moved a few of my songs to other media players after editing their tags within iTunes. And indeed the tags and/or artwork were often displayed messed up and/or incorrect, some times partially and some times completely.
    Some people were referring to the version of the ID3 tags being the issue, while others suggested using the "convert ID3 tags" feature. I myself am a little bit confused. "Converting the ID3 tags" wasn't available for my M4A files and once I performed it for my MP3's I didn't know which setting I should apply or what version to choose. I chose one version randomly but I'm not sure what happened.
    My goal is to make my music library able to play and display my custom metadata on the majority of the popular media players. I hope that firstly this is possible and that secondly it won't be a solution which requires me going through every single song individually.
    I really hope that all those years work on my library wasn't for nothing.
    I'm using a MacBook running Snow Leopard 10.6.8 and my iTunes version is 10.7
    While my music library is more important that my iTunes version, I do like iTunes 10 more than 11.
    I apologize for any grammar mistakes, since English is not my first language. Thank you all for your time and any suggestion is welcome.

    Hello turingtest2 and thank you for your reply.
    In response to "a possible cause of problems is multiple embedded tags", what exactly does that mean and how can I avoid doing it in the future?
    Anything ripped with iTunes should get a single tag. If multiple tags in some of your older mp3 rips are the cause of the problems when you try to access the files elsewhere then you should apply the suggested remedy selectively, not to the whole library indiscriminately. Once fixed you shouldn't have the problem again unless you use different ripping software. If so check the options to ensure you generate a single ID3v2.3 tag. Downloads from elsewhere are pot luck.
    If I use Convert ID3 Tags>None before converting to v2.3 as you suggested, how many times is "several times" and why do I have to do it more than once? Also, what are your thoughts on 'v2.3 vs. v2.4'?
    Several is at least two, but more could be needed if a file has both v1 and v2 tags in multiple languages. If there are two tags, the first conversion to none should remove the first one, and the second conversion the second. Experiment, And stick to v2.3.
    In response to "the process removes any embedded art but otherwise preserves the data that iTunes knows". All fields excluding cover art remain the same? Does that mean that I will have to start from scratch and apply new cover art individually for each album? That would be too time consuming given the fact that I embed custom art.
    Yes, everything but artwork is held in the iTunes database and is restored with the final Convert ID3 Tags... v2.3. Use Doug's scripts SaveAlbumArtJpeg before you start and RestoreArtworkFromAlbumFolder afterwards to save and the restore your existing artwork.
    Also, what happens with my M4A files' metadata? ID3 tags are only used for MP3's, right?
    Yes, m4a/aac files have a different tag mechanism. Multiple ID3 tags is just one possible issue that you might have. You said:
    So, I experimented and moved a few of my songs to other media players after editing their tags within iTunes. And indeed the tags and/or artwork were often displayed messed up and/or incorrect, some times partially and some times completely.
    It might be worth going into some more detail about exactly what differences you noticed. iTunes can automatically associate (instead of embedding) artwork when it can match the album in the store which could be why some tracks didn't get artwork.
