As of iTunes 10.6, iTunes has been having strange syncing issues with my iPhone. I had to delete all my backups (it said that they were corrupted), and every time I sync, I have to wait for it to re-copy the same 54 songs. The songs are weirdly chosen: some of the Halo soundtracks, plus one Glee song. As far as I can tell, the songs share nothing in common (no playlist, I haven't been listening to them, etc). They remain on the iPhone after a sync, they're there, but whenever I try to sync, they re-copy.

 

Ideas?

    Are they in a Smart default playlist like "recently played" or "recently added" which you have checked to sync ?

    I should've mentioned this in the OP: they aren't. I intentionally don't sync smart playlists or genius mixes precisely to ensure my syncs are consistent and the music isn't constantly changing.

    Same problem here, with 185 songs!  Any news?

    I just noticed something.  I own the Beatles' boxes issued in 2009, both the Mono and the Stereo versions.  I noticed that the songs iTunes is repeatedly copying are exactly those whose albums exist in both collections.  This means they have exactly the same name, year, and artist labels (album titles are different, because they contain the words "Mono" and "Stereo").

     

    I made an experiment and excluded them from the list of synced songs: the problem disappeared.  As I put them back on, iTunes started recopying them again.

     

    Definitely looks like a bug in iTunes.

    Glad I'm not the only one experiencing this.

     

    Building off what rbavila wrote about Stereo vs. Mono, I noticed that the songs that keep re-syncing are actually encoded in mono sound, not stereo. I can't find any Smart Playlist option to let me see if these 53 songs are the only mono songs in my library. Other than that, some of them are VBR, some aren't, but mono seems to be their shared trait.

    You might want to try a Restore of your phone.

     

    I am having the same problem with iTunes (currently 10.6.1 (7)). Every time I sync my iPhone 3GS, about a dozen Mono Beatles tunes are re-copied to the phone, even though they are already there. They are from boxed sets of Beatles CD's I purchased years ago. Each Mono cut from an early Beatles album has "[Mono]" appended to the title. They are all encoded in AAC, low complexity, mono, 160kbps. They were encoded with iTunes 6.0.2, Quicktime 7.0.4.

     

    I agree it appears to be an iTunes bug.

     

    Does anyone know... Is there a way to do something equivalent to "deleting prefs" for a flaky app... except somehow resetting all the music sync data for the iPhone instead?

     

    My only thought is I might try a Restore of the iPhone. I'd have to be sure to get all my photos etc. off of it first, then Restore through iTunes and reload everything. I know this "last resort" option is there for fixing many problems, but I don't want to try it until I'm sure it's not just an iTunes 10.6 bug in the first place.

     

    You might want to try a restore though. Just make sure you have all your photos, videos etc. off of there and backed up somewhere first. You do it by choosing "Restore" from the itunes window when your phone is plugged into the computer (it can't work over Wifi).

     

    Please post back your results if you try it. Thanks.

    I've had this problem for a long time.  I'm a musician and have stems and mono mixes in my iTunes folder. 

     

    I noticed that the hundreds of problem songs are in mono.  I just converted them to Stereo and this seems to have 'solved' the problem.  I put quotes around 'solved' because it's really an annoying workaround.  This bug has persisted for years and Apple should get it fixed.

     

    Until they do, convert the problem-songs to Stereo.

    And remember it will all need to copy one last time.

     

    Also note this problem only seems to happen when you have "Convert higher bit rate songs to..." checked.  If you have the space on your iphone, leave that unchecked.

    Also remember after converting to stereo you'd need to delete the mono files from your iTunes.  OK - good luck.

    Just to bump up this thread, and to add another bit of info: I've just synchronized my whole library to a 1st gen Apple TV, and the problem doesn't happen.  Maybe because of what livinginaboxers said about downconverting the songs to 128k AAC.  I do have this setting on my iPhone, but not on the Apple TV.

     

    A question about converting the songs to stereo: does this mean necessarily duplicating the original mono track (and as such the files will be twice as large) or is there a smarter way to do it, like e.g. the joint-stereo feature of MP3?

     

    Cheers

    I'll add to this. Every time I sync my iPod Touch, it resyncs the same 90 songs that are in Mono. Every time. Very disappointing that iTunes keeps doing this.

    I have this problem as well.  I think it has to do with the 'testing' of your library for unauthorized music.  I.E. music not purchased from iTunes.  I could be wrong about this, but it seems to follow some of the songs that I see resyncing.  Funny, Steve Jobs started out his career creating a device that would steal long distance from AT&T and then became obsessed with anyone he suspected of stealing from him   I still love you Steve, but you know this is true.  That said, you remain the most amazing guy to come along in a long long while !

    I was trying to figure out why my OTHER on my iPhone is up to 17GB. iTunes keeps recopying the files made with the Voice Memos app, and my last sync OTHER increased from 17 to 17.1 GB. Off course the Voice Memo files are MONO files, because the iPhone only has one Mic and one speaker (for recording that is).

     

    Anyone else having this problem have an oversize OTHER section (in yellow) on your iPhone?

    I have this same OTHER problem, in addition to the recopying of 360+ of my 1200+ songs, My OTHER sectiion is up to 3.2, and this is only the 3rd time I've synced since I got the phone last week. I'm going to uncheck the Voice memo sync.

     

    I'll also look into converting the mono files to stereo. How is that done?
