I agree with @
GOOD GRIEF that Hip Hop is a culture. I just wouldn't necessarily call it "black culture"... maybe "urban culture" like @
Phil Banks said. Because I think of Hip Hop as a culture and not just a form of music, I DO think there can be guests in Hip Hop. I just don't think being a "guest" is necessarily based on race. Hip Hop is something you ARE, not just something you do. Someone can do the music portion, even exceptionally well, and still be a guest because they are primarily of a different culture. Likewise, there are certain people I would describe as "Hip Hop" who don't necessarily rap or make any music. It's just the cloth they are cut from. At least that's how I see it.
