4. Interpol -- "No I in Threesome"

You might say you threw this song on for a laugh, but seriously, including this plinky new-wave romp might hint to your girl that she needs to go the extra mile to touch your hollow, jaded heart. (Just hope she doesn't hear all the lyrics.)

3. Nine Inch Nails -- "Closer"

Time to find out how close your lady wants to get to you. And if that sweet young thing has a naughty side. A very naughty side. (Sorry, we had to embed the clean version.)
