"Ravel's Bolero" (gentle) and Stravinsky's Rite of Spring (violent, not for the faint hearted).

I suppose if you're really Gothic you might add Orff's Carmina Burana but I'm not into that. What I mean is, if a woman liked it I would be really scared of her.

These are for use during sex, most pop tunes are too short for this purpose. Also on the short side, the theme from "Hawaii-5-0"

I've not actually dared to try these, they're only fantasies.
