Q: Music not syncing after iOS 7 update

I think some of us can sync playlists when they deleted some "corrupted" songs.

Since these "corrupted" songs can be synced when I try with iOS6 iPhone 4 with no problem, I wonder what kind of "corruption" is. Apple should answer.

Also, I don't want to lose any song in my playlists.

Just tried deleteing those 2 corrupted songs from itunes completely(including itunes media folder), then re-enter them from my music folder.....

still doesn't sync up

so it seems like is not the songs original file that are corrupted.....but the update process makes those songs in itunes look corrupted, causing it cannot sync with ios7

No it didn't. As soon as I updated iOS 7.03 and latest iTunes, can't sync music OR movies.

I have had the same issue everyone here is describing and I have tried numerous solutions that have been posted by users in this forum thread.

I have iPhone5S, 64G, iO7.03 and iTunes latest and I cannot get my music to sync.  This is a HUGE issue for Apple and I do not see anything posted by them for a solution yet.  The only songs that are on my iPhone now are songs that are from iTunes that I purchased (cloud).

Frustrating at best. 

i am also having the same problems -- although, after waiting for over an hour, my phone finally got past the "waiting for changes to be applied stage" so i'm luckier than a lot of people.

unfortuately, all the songs that were on the phone before the upgrade, and look like they still are on the phone, are apparantly not on the phone, and are all being re-synced. i have no idea why. it wouldn't even be such a problem, except that i have 9000+ songs, and they are all being re-copied over to my phone.

it's been syncing for a full 24 hours, and only 5000 songs have been copied. is it normal for it to take so long?

APPLE, FEEL FREE TO CHIME IN AT ANY TIME.

it's frustrating that one person managed to get through to apple and was nice enough to share what apple said (or didn't say) on this one thread (out of hundreds of others). but, do we really have to get our information from a guy who talked to a guy at apple who said he'd call back?

C'MON APPLE, WHERE'S YOU'RE CUSTOMER SERVICE?

any feedback, even if it's just to say "we know and we're working on it" would help reassure people that there will ultimately be a solution. right now, it's just crickets, and that *****.

/end rant

Hey guys, this worked for me.

Applications > Utilities > Disk Utility

Select the partition you store your itunes and music on.

Click on "Repair Disk Permissions" wait for it to finish. Usually it should take about 15 mins.

You should then be able to synch all your music to your iDevice.

Hope it helps!

No luck. Sorry.

The trick about duplicating my playlists (and deleted the originals) worked!

Beware though of select the newly duplicated ones before syncing, as the old ones leave the iDevice without music (cant find them and therefore delete the music)...

This method didn't work for me, either.

I belive all these issues boil down to seemingly 'corrupt' music files in iOS7 envirnment.

(note that these files are not corrupt in iOS6 environment so there is nothing wrong with these music files. iOS7 is to blame)

I wonder anyone succeded in transferring these "corrupt" files to iDevices.

Of course, we have to pinpoint these corrupt music files first by trial and error methods. Finding only one music file will do for testing.

If not, we only have to wait for Apple to fix it. Especially, Apple engieer has to find out why iOS7 makes all these music files corrupt.

So a pattern I am finding is that nearly all the music files that I have ripped from my personal CDs will not play on my iPhone, but all of the ones that I have purchased directly from iTunes are fine.

Ok folks I got my iPhone to sync and it's a different solution from what others have posted. Furthermore it seems that what works for one person may or may not work for someone else. Conclusion? ***** slap it. I'll explain. I decided since powering on and off and hard reset did not work I would do a restore. For the past few months I've been backing up to iCloud, but for safety sake I decided to do a backup to my PC as well so I "synced" my iPhone to my PC, changed the setting from iCloud backup to Desktop back up and that seemed to cause my phone to "snap out" of its funk. Since the desktop backup is more comprehensive than the iCloud backup, it forced my iPhone to transmit data TO my desktop, something it hadn't done in a while. After it was done with the backup, I gave it one more chance before hitting restore and PRESTO! it synced, no problem. So my conclusion is try and force it to do something out of the usual routine. Altering playlists will not do it. Change settings, change backup change something that will cause it to do something different. Hope this helps someone.

No luck for me either using the repair disk permission.......still cannot sync the 2 corrupted songs

I've always backed up to my PC, but I just tried switching to the iCloud backup and then back to the PC backup.

This time it got stuck for a while on the "waiting for items to copy" message instead of on "waiting for changes to be applied," but it still didn't work. My music files are still missing.

I spent 2 hours on this issue and this is what worked.

-Restarted itunes after upgrading to latest version

-Restarted iphone

-created a playlist with "all music in it"

-on itunes, clicked on Summary

-Backed up phone to computer

-then I synced again and it worked!

Got lucky I guess.

Yes I had this issue also when I decided to sync my iPhone after the ios 7.03 update and I ended up with 30GB of Other! I sorted the issue by the following:

1) I did a soft reset on the iPhone using by holding the Sleep and he Home button (Not sure this actually was important or not but I did it so I list it)

2) Plugged the iPhone into my laptop

3) When iTunes connected with the phone I looked at the 'Info' in iTunes and seen it was still showing 30Gb of 'Other'

4) Tried to 'sync' just in case

5) While sync was running I selected through the category tabs for the iPhone content

6) I went to the 'Info' tab again and seen that the 30Gb of 'Other' was now just under 1Gb

The phone then synced properly.

I am not sure if this was luck, I doubt it was the soft reset but maybe an iTunes and iOS7 issue but in all honesty I have no idea except that this worked for me, shame it wasn't as easy to pop back to OS6 ;-)

HTH
