It's hardly a major secret that the majority of purchasers of hip hop are white - figures tend to vary between 60 and 70% - so one would assume that the marketing of the genre would be geared toward that demographic.
Sad Ken - look, I'm white and I've bought and DJed hip hop for years. My point wasn't about who should or shouldn't buy the genre, it was that the negative aspects associated with it that other posters have alluded to are as much to do with commerical packaging to people who live outside "the hood experience" than any sense "of keeping it real". To put it simply, the overwhemingly white hip hop audience are more likely to buy 50 Cent the Gangstar as opposed to 50 Cent the Successful Buisnessman.
