does happen) and nothing else is so ridiculously shortsighted.
As for why I don't like metal--as a vocalist, I absolutely hate growls, as well as shrill pitches ala Rob Halford, Dio, Or Axl Rose. Metal tends to have a lot of one or the other. Don't get me wrong, I like some metal songs, but as a genre, those are few. My tastes are pretty eclectic--from Air Supply to Korn. I like blues. I even like some country, though I would deny that to my wife. But mostly, the reason I avoid RBN is because most of the songs are unknown to me and my crowd.
So it has to be popular to be good. A disappointingly common mindset.
Well, your loss.
