I would be interested in knowing some kind of number for people who, after a steady diet of Britney Spears and Lady Gaga and whatever-god-awful-act-is-next, finally say "enough" and cast about for some music that is more filling. They may discover classical, or trad folk, or bebop, or Gilbert and Sullivan, or some other brand of music that isn't as ephemeral as the pop/rock/rap they are force-fed by the mainstream media. I think there is a movement in that direction, even if it's only a trickle, but I would be interested in seeing it quantified somehow.
