Probably not on anyone's list...but I really like Maxi Jazz from Faithless. Not so much a rapper...but definitely knows how to bring it smooth and silky. Also prefer... Rakim MC Tee (from Mantronix) Q-Tip Doug E. Fresh Slick Rick and another left field entry... Dr. Octagon
I'm more into the lyrical cats: Nasty Nas AZ Slaughterhouse Royce Joe Budden (forget Love and HipHop, his introspective music is good) XV (newer) Em (older stuff) Fabolous When I work out though, French Montana keeps me going. Haaannnnn! lol
I can never do these, for me my preference is constantly changing. Other than Jay and Pimp C/UGK, its usually just what I'm feeling at the moment. And right now that's Slim Thug: Boss Life, A$AP Ferg: Trap Lord, Yo Gotti: I Am. Feeling Rocko's new mixtape as well. I'm usually down with Kanye too. I don't get into the ranking's because I couldn't care less and I like what I like. What can I say, I'm from the South mane... Love that trap music.
McDougall's McDonald's MCS MCI (I think they're defunct now) AND LAST, but not least: Spoiler Oh-OH! OH-OH!
