Lawing:

I can't believe the LW really has to ask what she should think about this. She needs to ask him: Is it the sound of the music that gives you "energy" or is it the lyrical content?

Exactly. If he requires jackhammer noise in order to get it up, that's a different deal (perhaps still a deal-breaker, but in a different way) than if he needs to hear "I sliced her into little pieces then ate them with salsa" kinds of lyrics in order to get excited about having sex with a girl.

Ah, forget it. They're just two different levels of yuk.
