I don't know if this is an answerable question or not, as it was met with some derision at the Apple support forums, but I'll try anyway. I purchased a song from the iTunes music store and attempted to add it to my iPod, since I don't have the iPod and iTunes synched, I add things manually. When I tried to put this song on my iPod, however, I received a message saying that the file was not copied because my iPod already has music from 5 separate accounts. I have only ever used my own account, so I'm not sure what the problem is. I'd like to know how to see which songs were purchased by which accounts, if I could, or any other solution to the problem would be welcome. Thanks in advance!
