Dumb question, but I'll answer anyways...
Easily good music. I don't know any of these super thug rappers personally, so why do I give a shit if they have any street credibility? Seriously...it seems like 3/4 of these ''gangster rappers'' are entertainers, therefore they're, at best, half real, which is kind of like comparing them to Midget Mac; they're half a G.
Phil Collins is coo' as fuck, too...he doesn't have any street cred, but he'd probably be able to run up into a lot of these rapper's girls.
