fair enough. I don't mind a garish sound pallet within moderation, but I think rave music has always been garish vis-a-vis the connoisseur's choices, deep house, detroit techno etc.
It's hard for me to pinpoint exactly when this sort of sound gets less interesting, because it undoubtedly does. I think it's to do with a certain kind of theatricality or absurdity. Things going over the top etc. Once that abandon vanishes and it's just plod for the sake of plod I'm not interested. That Dylan tune is quite silly, but that's why I like it.
