Always seemed a bit racist-y for audiophile circles to ignore Rap ("SQ!"), while Punk, old Metal, etc. are regularly brought up. Maybe not in skin color, but at least in musical heritage (Rock v. Jazz most obviously). Note how the rockish Beaties were an exception of the silence years ago. And I always think of Robert Christgaus' great gateway review...
Course this is all decades ago now.
Time for some morning Public Enemy. This Henry Mancini SACD is putting me back to sleep.
