Hey, I am on the latest version of iOS7 / iTunes but my phone doesn't sync my music library anymore. I have around 5,000 songs in my library and everytime i remove all music and try to add it again it only syncs around 2,200 songs. None of my new purchases is synced either. Apps and everything else seems to sync fine, just the music doesnt sync. I resetted the phone multiple times, set it up as new device etc but nothing seems to help. Any idea ? Is there any other tool besides iTunes to sync the music to my phone?
