Jedi Mind Trick - Uncommon Valor (I'd recommend any who wants to hear some rap with actual meaning to give it a listen; it's about two men and their experience in the Vietnam war).
I like a very small amount of rap; two artists mainly, Jedi Mind Trick, who're very political, none of this crap about busting caps in people's deriers! Then Sage Francis, who's just a bit weird and I can't really describe xD
Expendables: Sacrifice (the guitar in this song is GODLY)
Edit: DOUBLE MUSIC RAMPAGE.
In the time it took me to post, my song changed to Joe Esposito; You're the best around.
