To call something a "black name" or "black music" bothers me. I don't think the subculture from which these things come is inextricably linked to the skin colour of the people who typically comprise it. Furthermore, I think that using terms like that is going to perpetuate the false idea to our next generation that there is a "white world" and a "black world", and the people who come from these places are very different from each other. I don't believe that will have positive consequences.

PS - I just don't think these are healthy distinctions to draw.
PPS - Variations within people groups are bigger than variations between them.
