I actually prefer no "background" music at all. The sounds of lovemaking are musical enough, at least if you're doing it right. I'm sorry, but I don't need Smokey Robinson or Billie Holiday butting in. I'll promise to devote my full attention to them later if I can devote my full attention to her now.
Oh, you mean BEFORE the interlude? In that case, I'm with Tom (Twl)--I'll play Sonny and Cher or Grandpa Jones if that's what she digs.
