My music is not syncing with my iPad mini after iOS 7.0.4 update!!

Same problem. Did not found a solution yet.

This problem can be fixed be re-initializing all settings. Restore and re-sync. Long process but it work for me.

Can you explain this to me? How do you re-initialize all settings? What did you restore to? I use my iPad to teach music and movement classes and have not been able to for over a month because of this issue. I went out and bought and android device, but it is complicated to convert playlists from itunes. This has been so frustrating.

Before re-initialized all settings, be sure to backup your iPad with iTunes on you PC (not with iCloud in iTunes). When this step is completed, eject your iPad from itunes. Then go on your ipad. You will find function for re-initialization under "General menu" in the "Settings app". This function is at the bottom of this menu. In this function there is many options. Choose "Re-initialize all settings". This will reset your iPad just like it was when you bought it. When its done, replug it on your PC and with itune, restore your iPad with latest backup you have made. When restore is completed and when your iPad is fully reconfigure. Then you will be able to re-sync your music and other stuffs. This can be a long and tedious process. But it work for me. If you need more assistance, go the nearest Apple Store. They will help you. Be warned : I do not take responsibility for this. But It worked for me many time with my iPones and iPad. IOS upgrade is always a mess.

Good luck !

I did this and still can't sync anything. Apple better address this issue on the next update.
