Hello everyone! I have the 4s iPhone and had him synced already a few times, now suddenly it does not sync my music. I searched the web for some answers and found i can use the autofill button to add albums to my music folder in the iPhone, BUT my previous albums can not be deleted, when i empty my music tab in iTunes i still have some albums left in my iPhone. i tunes does not detect those albums and i can't access them in any way to delete them. Music sync box is checked. Anybody?
