another vote for DMB's "...Crowded Streets." There was actually an article on best songs to **ck to and this album was it cuz you didn't have to worry about changing a CD for different moods. It just kinda flows.
If you want the "makin love" stuff: U2 is good, Enya, Dido... my ex played this one singer from Ireland or something. Lorena McKenitt or something... bugged me
My friend told me that her roommate used to play Mono's "Life in Mono."
Adding in: I completely forgot about Janet Jackson. I am a lil conservative and all... so her new album's slow songs were like "WHOA!" But it would work perfectly. There is one song that just gets right to the point.
