I just noticed today that I can't seem to play most of my music from my iTunes on my iPhone running iOS6. The very same songs and playlists are on my iPhone 4S and work fine, but on my iPhone 5, a lot of songs won't play at all, and others, some songs will and some won't. I do NOT have shuffle enabled, yet I will tap a given song and it either won't play, or it'll jump to another song and sometimes play it, sometimes not. I tried rebooting it and selecting manual sync, but that didn't help. Am I doing something wrong? Every iPhone I've had has ported smoothly, but this one is indecisive! Has anyone come across this? If so, please help. I'm also going to post this on the iOS 6 thread too. Rob.G had the same issue and I don't think he got a true answer as to whats wrong!
