Carcass - Heartwork
Morbid Angel - Everything after David Vincent left the band except for Illud
Slayer - Undisputed Attitude
Metallica - Garage Days
Korn - See You on the Other Side
Otep - Pretty much everything they ever did, except for a few songs here and there and almost the entire Atavist record (Fists Fall was the only song I can say I "liked").
Can't think of anything else at the moment.
