All the following iTunes Matched songs appear corrupted and will not do the following:

  • playback in iTunes
  • convert to 128 for syncing to iOS devices
  • convert to MP3/AAC/AIFF/etc


After iTunes Match and subsequently "upgrading" my library, these songs won't do any of the above.  I've tried deleting them and redownloading from iCloud, but they still won't work.  I've tried converting them through both iTunes and Audacity, but the files appear corrupted and will not convert.

    Out of about 10,000 downloaded matched tracks, I found about 40 that were corrupted in some way or another. "Get Info" identifies them as MPEG files, not Matched AAC.


    I can add to your list once I get home from work. Somehow I managed to create a playlist that can detect the corrupt files. If a subsequent redownload grabs a good file, the track disappears off the list.


    Here's one I can give you right now:

    Morganspaziergang - Kraftwerk - Autobahn

    The question that needs to be asked and confirmed here is were these tracks actually matched and replaced on your machine?  Or were they your own tracks that got uploaded.  If they were your own tracks that got uploaded it is possible that they got corrupted when they were uploaded.  If that is the case you should be able to completely delete the tracks from itunes, and itunes match, then restore them to itunes from a backup and let itunes reupload them.  If they are in fact matched tracks and your original file has been deleted from your computer, and replaced with the matched track from apple, then they should be confirmed and reported to apple. I can say that I have matched and downloaded Lullaby by The Cure, and the version I downloaded from itunes works perfectly.

    These were matched tracks. I even used the playlist trick from MacWorld to make sure the list I was downloading from was a "matched" or "purchased" track. When I would do a mass download of Matched AAC tracks, the file would disappear from the Matched playlist, show up in the "corrupt" playlist, then disappear from that list if the file checked out.


    I will periodically go back and attempt a redownload of the corrupt files. Little by little the list shrinks a couple of files at a time.


    Like I said, I've only had ~40 bad out of ~10,000, so the percentage of bad files is incredibly small.

    My reply was intended for the original poster.

  • Hawk00eyed Level 1 (0 points)

    Yep, they were "Matched" files, as opposed to "Uploaded."  They all show as 256 kbps, which isn't a bit rate that I normally import at.  Basically I also did a mass delete/download of all my songs that could be upgraded (ie 256 kbps, iTunes Matched). 


    I would try to reburn copies from my CDs and re-match, but I don't have them with me at the moment.

    I have this exact issue, and the list of songs that won't transfer to my iPhone or play in iTunes actually grew after a couple days (was just a mix of Joanna Newsom songs, and now a few Radiohead are thrown in).  The songs were matched, but can't play in iTunes.  I deleted them from iTunes (not iCloud) and re-downloaded them from iCloud, but no go.  The iCloud synced versions will play on my iPhone without a problem.  Very strange.

    I submitted the issue to the Express Lane, and the reply was:


    "When using iTunes Match and switching the files to be used in iTunes, some purchases may have already been corrupted and are unable to be used based on the third party site that was used." and a link about iTunes Match status icons. >.<


    Here's a partial listing of corrupt files I've found. Repeated deletions and redownloads have no effect.


    Full of Fire - Al Green

    Mr. Moonlight - The Beatles

    It Won't Be Long - The Beatles

    Inwards - Big Country

    Chance - Big Country

    The Storm - Big Country

    Hard Headed Woman - Cat Stevens

    The Makings of You - Curtis Mayfield

    Jump Study - Dr. John

    Angelina - Herb Aplert

    Little Girl Blue - Janis Joplin

    Up From the Skies - Jimi Hendrix

    Ladies Room (live) - KISS

    My Little Red Book - Love

    Time Has Told Me - Nick Drake

    Jägerspiel - Laibach

    Their reply doesn't even make sense, these are all songs that are "Matched" so regardless of whether the original was corrupted or not, redownloading them from iCloud should get you an uncorrupted file, not a file that doesn't even play.

  • Hawk00eyed Level 1 (0 points)

    By the way, how did you go about making a playlist that showed all the corrupted files? 

  • DarkAudit Level 1 (0 points)

    I had a smart playlist with these settings:

    Bitrate is 256 kbps

    Media kind is Music

    Kind contains MPEG

    iCloud status is either Matched or Purchased


    I'd used the playlist to find 256 kbps mp3 files, but then I noticed some of the tracks didn't leave the list after downloading. And they wouldn't play.


    I also discovered that when upgrading the lower bitrate tracks, they would show up in this new playlist while the download was pending, then disappear once the file checked out as good.


    Still holding at 39 bad tracks out of over 10,000. good percentage-wise, but of course some of those 39 are tracks I like to listen to.

    Change the extension from .m4a to mp3 and they will most likely work.  I've ran into several like this as well.  This isn't a fix for the fact that Apple has the file type set on the files or the fact that Apple is sending out mp3's instead of m4a, but you can at least play the songs until they fix it on their end.

  • DarkAudit Level 1 (0 points)

    That worked, sort of. The bit rate is lower than it should be (can't say for certain if it was the bit rate as the original mp3 I started with). But that's good to know. I will add that information to the ticket I already have open.

  • Hawk00eyed Level 1 (0 points)

    Interesting, yea that got it to play.  Very strange.  Thanks MichaelBG

    I reported the list of my corrupt tracks to Apple right after my previous post. That was the last i've heard. Corrupt files are still corrupt.
