Duplicate songs on iPad
I recently purchased the Beatles Box Set from iTunes and, for some reason, two of every song and video in the set ended up on the iPad. There are not duplicate copies on iTunes on my Mac. I tried deleting all of the duplicates right from the iPad, but they came back the next time I synced. Any ideas why this has happened and how to remedy it short of deleting all music and resyncing?
