OK...I suppose I'll throw a few things out there:
For workouts, I listen to a lot of Rage Against the Machine, mostly from "The Battle of Los Angeles" and "Evil Empire".
Here's a few other faves:
Bob Marley "Legend"
Dr. Dre "The Chronic"
Public Enemy "It Takes a Nation of Millions"
Jay Z "Vol 2...Hard Knock Life"
Linkin Park "Minutes to Midnight"
House of Pain "House of Pain"
LL Cool J "Bigger and Deffer"
I'm sure I can come with a few more, but this is a decent start.
