Dereks post about disrespect to women sorta turned into a post about rap.
I'm more of a metal head but I listen to beats to switch things up, and am always looking for more quality material.
So post up what you listen to, and no garbage-rap please (Lil Jon and those other no talent ass clowns

)
A few I know of right now:
Mos Def Dj Shadow
Blackalicious RJD2
The Roots MF Doom
Aesop Rock Diplo
