I'm with lonerstoner and rap master. Yall left out some though. My fav's are atmosphere, brother ali, common, devin tha dude(both of his cd's are the ultimate stoner rap), gangstar, ghostface killah, immortal technique, j-zone, louis logic, mos def, sage francis, and talib kweli.

If you like atmosphere, you gotta hear Felt 2: A tribute to lisa bonet, which is Slug and Murs.
