I gave examples of whole social cultures that revolve around a musical genre. And I'm not saying there isn't some value in whatever music they like. But do you think it is just coincidental that tastes in music, art, sports, etc aligns so closely with cultures where people have a vested interest in fitting in?
I remember as a kid trying SO HARD to care about professional football, because it was cool to like a team, or at least to be able to talk about a game that happened on sunday. I gave up after a while. I have friends now that if I really want to fit in with, I need to like expensive scotch and enjoy talking about it (I'm sure I could get used to it, but my natural reflex is to spit it out), or maybe I should take up golf, and try to really care about what to me is a deadly dull sport.
south park has made great fun of this with their portrayal of goth kids complaining that everyone is conformist and then demanding that their friends be conform to be just like them, like the same music they like and wear black.
Christi's work required a ton of money, that had to come from somewhere. It clearly wasn't the mass appeal, since he didn't sell tickets or anything. It was rich people who wanted to impress one another with their sophisticated sense of art. (or maybe just with the fact that they had so much money burning holes in their pockets)
