i think one of the track 01's, and the track 02-05 are all the same artist; the other track 01 is different. i have gotten a bunch of music from other people, a lot of it stuff that i'm not familiar with and haven't listened to yet. what's weird to me is that my old i-tunes library doesn't have these orphan songs, but when i imported that library into the i-tunes on my new computer, they appeared.
