ok so the workarounds seem pretty unreliable. I have a question - if you do the full restore as a new phone, does that fix the problem for good? So far I have been reluctant to take such a major step, but it has to be better than constantly wiping all the music and re-adding it.
No. Like the many other "solutions" discussed on this board, in my experience, a full restore does not fix the problem for good. After I did a full restore, the sync was successful once or twice and then returned to the same behavior.
After dealing with this for months now and trying all user-suggested fixes, I am resigned to the fact that syncing is simply broken with iOS7. I'm keeping my fingers crossed for a fix from Apple. The AppleCare senior advisor that's helping me has supposedly submitted a "trouble ticket" to the Apple engineering department. Everyone else here should contact AppleCare and try to do the same.
I've suggested this before, but it also wouldn't hurt if we can somehow get some tech media coverage of this problem to put some pressure on Apple. Right now, a Google search of this problem only brings up these user message boards; no blogs or tech sites seem to have covered it.
In the meantime, I'm using the "manually manage" option and dragging over my new music & playlists onto my phone. Not ideal, but better than wiping and re-adding the whole music library each time I want to sync.
