Music

We see in movies all the time, when there is a couple having sex or making love there is music playing. And you can always tell what kind of sex they are having by what kind of music is playing. My fiance and I don't play music during our sessions (but I would love it) but I always have a song playing in my head during our sessions. Am I the only here who does? If not... what kind off music do you play? And is it in your head or blasted in the room?
