iTunes won't sync music.
My iTunes will play all of the music I have, however, when I sync it to my phone, it completely skips out the part where it syncs the music. The music still shows on my phone, but when I press the track to play, it skips through all of the tracks really fast without playing anything. The only music that I can actually play are tracks that I have bought from iTunes. Does anyone know how I can fix this?
