You add like a 100 other so called rap artists of today. Tell me where is the art in the Bs music they put out.
The 3 you mentioned are top. ATCQ the greatest hip hop group of all time. Eric B and Rakim, classic. Mos Def, Fu Schnikens(original old school group, not around anymore). Blackmoon, Mobb Deep who had two classic LPs, the infamous and hell on earth but then they started making music for the masses.
