I have the U2 Special Edition. It's so cool! I also got the Complete U2 - 447 songs. The only other music I've purchased from iTunes so far is Sinister Dexter's "Dexterity." They're a sort of swing band, and I know a bunch of the guys, so I was more than happy to support them. They're excited to have their album on iTunes! I also have some of my CDs that I'm slowly uploading to it.
I love the Playlist feature. I've got one called "workout" that's got all up-tempo songs.
