I have moved my itunes library to a new PC. All but approximately 100-150 songs will synch to my ipod. It says "not authorized" but when I authorize it, it says "already authorized"? I thought possibly they were DRM files, but I can't tell?
Any ideas how to get all my songs synched on the ipod? They are in my itunes library on the new PC.
iPod nano, Windows 7
