hmmmm.....most good rock you can dance to anyway. Wasn't it called rock and roll once? A place where people could dance and feel liberated and forget about all their worries? The two cultures seem to run by a different set of rules different rules, but they're both a means to the same end, a good time. Maybe young people who are going through some difficult shit in their lives can't identify with the empathy of loved up dance choons. Nirvana have got a lot to answer for (not their fault...blame marketing...I do).
There is hope though ;) The Flaming Lips "The Soft Bulletin" album has a few of the answers.
