Hey,
Ive had my iPhone for years now, but recently have had trouble syncing some songs onto my phone. I have 3 new albums I brought around a week ago, and they were fine for a few days. But when I synced with my PC they doubled up on my iPhone, and won't play. (although everything was fine in my iTunes library, and they play fine on that)

Anyone else had this problem? It's only happening to a few new albums I just brought.

I've tried syncing on iPad, another iPhone and also a touch, and it's happening on all of them, so it must be a problem with my library right? No idea what to do!

Any help would be greatly appreciated.
Thanks,
Dan
