Thats aboot it, i think.

Rage Against The Machine, Radiohead, Nirvana, Red Hot Chili Peppers, Ramones, S.O.A.D., Blink-182, Soundgarden...

Besides the more recent artists that have come out with only a handful of albums, I think the only artists where I own all their CDs are probably 2pac and Nas. Oh wait, I dont own either of their most recent releases, so nevermind.

Green Day, Nirvana, and I owned everything done by Hole up until Celebrity Skin.
