pick up a guitar and learn the solo from "warmness on the soul" (avenged sevenfold). seriously no woman in the UNIVERSE will be able to resist a guy playing that on his guitar. NO woman.
It's better to write your own, and make sure it's good. Now that I think of it, I wouldn't want to use other artists' songs as a way to get me laid. Sure I'll play them, but not, er, in the moment, so to speak.
