Yeah, this is always a big thing. If you can make it with that "I don't normally like Hip-Hop, but......" crowd then there's money to be had.
I don't know about you, but those people always piss me off a little bit. The supposed "serious" music people who think they're being all eclectic and shit by giving their stamp of approval to a couple of rap acts but probably couldn't hold more than a 30 second conversation with you about the genre as a whole. This is partly (or perhaps largely) just my own rap snobbishness coming through though, to be fair.
Anyway, I may be imagining this, but did I see you mention the new Wiley album somewhere else on the board? I haven't checked out anything by him in quite a long time but I'm really liking his new one.
