there'z so many rappaz that got multi'z that ya can't even tell no more...but if ya wanna go mainstream then I would say Eminem, Dipset, the Lox, and Lloyd Banks

and if ya wanna go underground then Tonedeff, Copywrite, jakki tha motamouth, and Vinnie Paz

and if ya wanna go old school then Masta Ace, Rakim, Kool G Rap, and MOP...
