Tech N9NE, no questions asked
Celph Titled, great punchlines, incredible voice, hard-hitting delivery
Twiztid, love their wicked lyrics and style
Reef The Lost Cauze, his last album was disappointing to me, but his debut was incredible and his AOTP stuff (just like Celph) is the shit
Dizee Rascal, best live show I've ever been to, tore the place up, and his albums were consistently fire
AZ, legenary rapper, isn't really consistent with his albums but has the best flow in the game IMO
Canibus, uncomparable voice and style, great lyricist
Bizzy Bone or even better Bone Thugs n Harmony, still listen to E 1999 once in a week at least, probably my favorite style of music, too bad Flesh had to get locked up again
Cage, twisted dude, but I just like his music
RA the Rugged Man, Die, Rugged Man, Die was outstanding and his stuff always delivers
Honorable mentions that just didn't make the list today, but could tomorrow
Slug
Obie Trice
Ludacris
Kutt Calhoun
Tonedeff
Eminem
P.O.S.
I left of a lot of Legends and obvious ones. I know my Hip Hop 101 but I don't listen to much of the "greats" a lot.
