Can't sync music anymore with iOS 8. All disappeared.

same problem here. i guess we have to wait for a fix in itunes or ios.

Same thing was happening to me on iOS 8.0 with iPhone 6 Plus 128. Three hours and no go. Slept on it and this morning I remembered that this seems a problem with every major iOS release and remembered what I was told to do then. So there's what I did and now everything is fine on all of my devices with regard to synching. Go to Setting-General-(bottom of the page) Reset-Reset Network Settings-Device Passcode-Reset Network Settings. Let the device do that and restart. Try again this should clear the problem. Up until this point the device and iTunes didn't even know each other from Adam. By this I mean that the amount of space available between device and iTunes and device itself was all messed up. Now everything is running smoothly. What does Network Settings have to do with anything, I have no clue just know it worked. Good luck. You'll have to retype your WiFi password after doing this.

i'll try this.

if you look on twitter a lot of people having this problem with sycning music.

//nope. didn't work for me. would be strange too, i dont think its something connected to network settings.

its cool how everybody comes up with a different approach to solve this 😉

//UPDATE2:

Nice. It seems to work now? HAHA 😀 nice. Thank you. !!!

HAHA. I'll check again but right now its transfering music

On phone go to Settings-Music then scroll down to iTunes Match and turn off. Plug phone into iTunes and all music should be able to be synced again.

I Also have the sync greyed out. I've tried the reset network setting and tried via cable and wi fi. I think this problem stems from accepting iCloud Drive when I upgraded to ios8. Does this make a change to the iTunes account and therefore stops all devices syncing?. I updated my iPad first but from then on I couldn't sync any of my devices through iTunes, even my old iphone 4 which is on ios7. I now seem to have no way of putting selected photos from iphoto onto my iPad through iTunes and the ones that were there before the upgrade cannot be deleted! Seriously frustrated and I won't be able to upgrade to Yosemite so looks as if Apple have conned me into making my MacBook pro useless!

I did do what you said but for some weird reason my phone keeps 9 songs - which can't be deleted for whatever reason - and when I uncheck the sync music button and click apply, itunes by itself checks it again and starts adding songs again. I am so angry right now. Adding songs manually doesn't work either - hasn't for ages tbh. Only work around I found was adding songs to a playlist and then syncing the playlist but not even that is working properly anymore. I'm at a loss. 😟

Edit: and the number of songs it synces changes constantly without me doing anything. >:(

I had the same issue - have you tried to reset network settings? this one did the trick for me

yeah, I reset the network settings and when that didn't help, I /tried/ to delete all my songs but even when I uncheck playlists or albums in itunes and then sync it, itunes checks them again by itself. It's infuriating. 😠

try to uncheck music completely in the left upper corner. or try to delete music on your iphone directly under settings. maybe you're having another issue.. i dont know.

I also have this problem with 128 iphone 6 plus. Twice I have deleted all music from iphone in settings, then sync. The first sync after wiping all music is always successful (1502 songs). A second sync and music library is still intact/playable on phone. From the third sync on, iTunes randomly deletes some tracks (all songs not purchased thru iTunes). If I sync again, any missing tracks I have tried to play will be restored and it randomly deletes others. I also synced music after a clean ios8 restore (without restoring from a backup), thinking an ios7 setting might be the cause. Exact same symptoms. The same iTunes music library syncs to my ipad air (also running ios8) with no problem. Very frustrating indeed. I'm off to the "Genius" bar to see if they can help. At least lots of people are talking about this problem now, so hopefully a solution will emerge....

Thank you, it worked for me. I did a reboot of iphone6 and my MAC after it was synching with the "Sync Music" option removed and got hung up. After the reboot contunued with a fresh synch with "Sync Music" checked. All music synched into iphone6. Before any of this I had reset the Network settings that another poster had suggested. Thanks all of you!

did that too. That's the part where it gets really crazy. When I uncheck syncing music completely, it "rechecks" itself while it syncs. Seems no solution is working for me. 😟 I'm just hoping for some update now to fix this.

Hey guys,

Having the same issue for two days now with my 128GB iPhone 6. Syncing 84GB playlist, and heres what seemed to worked.

1. Turn off Sync Over Wifi
2. Plug in via cable
3. Uncheck sync music
4. Sync
5. Disconnect
6. On the iPhone, sign out of iCloud
7. Reset Network Settings on the iPhone as well
8. Quit iTunes ( force quit to make sure)
9. Restart iTunes
10. Put phone in Airplane mode and turn wifi off
11. Plug in iPhone again
12. Check sync music
13. Sync.

This is a combination of all the solutions that I read worked for others, but no one solution worked for me. This only worked when I combined all solutions. My educated guess? iCloud is the issue. That is based off the fact that I tried every combination of the other solutions that did not include iCloud, and this did not work until I added the iCloud to the steps. Turning off iCloud by itself did not help though...
