Yeah, is there something wrong with that?
You answer in the affirmative, somewhat offended, and ask if that's bad for some reason. "No," she says with a smile that belies the offense you had assumed, "I was just listening to that on the way in." For a moment, you feel something. What is this sensation? Something akin to...hope? "It's not often," she says, "that I meet a guy into the same kind of music I am." Is she really talking to you? Maybe even expecting you to talk to her? Quick, say something!
Tell her how much you love his music. Admit that it's not really your thing. Ask what other music she likes.
