Whenever I end up making out, if there is music playing I don't hear it. Not going to bust the mood by digging thru my CD's looking for the "right" song either.
Ravel followed by Tchiakovsky's 1812 Overture and maybe some Roxy Music, Barry White, and 76 Trombones from the original cast recording of The Music Man.
Bowie's Low album, hands down the best album to !@#$ to. The "song side" for when things are freaky deaky and the instrumental side for when you're getting your groove on and closing the deal.
