Does it rock, or does it RAWK?

Quick note: I've been in a rawk mood for the past few days. I'm listening to some Metallica (the Black Album and Master of Puppets specifically), and I just spent an afternoon listening to Appetite for Destruction on a loop. I've got AC/DC all lined up next, but I'm looking for more. Suggestions? Shoot me a note.
