Besides Ice Cube (My number one favorite rapper)
my favorite is pacs voice, DMX has a good voice too, I like the deeper sort of raspy voices.
Jadakiss has a unique voice and DMX sounds like he swallowed a whole bunch of needles
Nah Eazy-E all the way, or you can just call him E. It really doesn't matter to him cuz he's the same person, whether serious or rehearsin' he's just gotta keep cursin ;) Seriously though, Snoop and Dre have good character in their voices, and Ja Rule is awful :S You can't tell what he's saying :D
DMX, maybe Ja Rule..idk about Bone Crusher, I haven't heard anything from him for a minute. Meth and Jadakiss have real distinct voices.Especially Jadakiss since he sounds like he's got gravel in his throat.
not the best but the rawest voice i think chali 2na has the best voice
