ITunes Match Gobbling Up Cellular Data (even though disabled)

Question

I've found a few previous threads that reference this problem, but it's pretty horrific especially now LTE is in the picture.
Despite setting the "Use Cellular Data" option to OFF (verified in both Music and iTunes settings), if you select music to be downloaded (i.e. click the cloud icon), iTunes grabs the music regardless of whether you are on WiFi or Cellular.
Scenario 1: I get a new iPhone5 and want to sync my existing music library to it. I have a playlist with all 2500 songs in it, so I go there and hit the cloud icon so all my music copies over. There's no way to pause the whole process - only individual songs - and no way to stop it using cellular data, so when I leave the house, my phone starts eating up my cellular data plan (2.5GB in 3 days, when most of my time was spent at home). I detailed this on my blog - http://lamejournal.com/2012/09/24/itunes-match-uses-cellular-data-even-when-you- say-no/
Still, it shouldn't be so bad, because I spent most of my time at home. Right?
Scenario 2: Your brand new iPhone 5 has problems staying connected to WiFi (see the many threads on this issue). What happens when it has problems with WiFi and drops off the network? Yup, you got it, it uses LTE instead. So while I'm sitting in my house, 10 feet away from a 802.11n access point, supposedly 'safely' downloading my music over my home Internet connection, my phone randomly decides it doesn't want to play with WiFi after all, and continues downloading on cellular instead. Isn't that great?
This is ridiculous. The option "Use Cellular Data" should do exactly what it says - when turned OFF, iTunes should not be downloading iTunes Match data from the cloud over cellular. I have 20Gig of music to download, and thank goodness I caught it when I did before being hit with enormous overages.
Hopefully this is just a bug and can be fixed easily and quickly by Apple.
Thank you!

Answer 1

I too queued up a handful of albums to download this morning, took a shower, walked the dog... and by the time I got to work, a text from VZW tells me I've used 50% of my (2GB) data for the month (2 days into billing cycle).  This is on a 4S with iOS6, with FiOS and Airport Express at home, so it should have finished the 750mb or so in the alloted 45 minutes, but the screen went dark, so iPhone took a nap instead of doing her job.
This is bonkers for several reasons:
1. If you queue several iCloud downloads, from within the Music app, there is no visible queue for the pending downloads. You have to go back into the artist/album to see the progress on each song OR enter the iTunes app to check the pending downloads.  WHAT? my queue is in ANOTHER app?*
2. Queued downloads continue when the app is "killed" from the task switcher.  I guess this is a feature, but there is NO indication of a data connection in use.
3. If the iPhone screen goes dark to sleep, it turns off wifi to save battery and any queued downloads stop.  They will resume, over any available data connection, regardless of user selected settings. This is true for partially downloaded songs and queued songs. If I wanted to use cellular to download, I would enable that setting.
4. Podcasts, while a different app from music, uses the same data storage and download queueing.  So if you have pending downloads that you can't see the progress of, you may wonder why podcasts aren't updating.
5. In music.app, if you have "show all music" set to on, there is no indication if an artist/album is available locally or in iCloud.  You have to browse into the tree to see the track names greyed out.  Or else you can toggle "show all music" in settings.  Why can't there be a toggle within music.app, or an iCloud/local tab?  While I'm ranting about Music app, PLEASE can we have a sort by Artist/Album/YEAR option like in iTunes on mac?
