In college it was Genesis and Ravel’s Bolero (from Bo Derek’s smokin’ “10” days). In my single days, it was a bunch of “MTMLT” tapes my roommates and I made that were a compilation of all kinds of stuff - rock, jazz, blues. Now that we’ve got tunes back in our bedroom, I’m looking for new ideas.
So what’s your background pleasure for pleasure? I mean, besides Barry White, of course…
I’ve heard some people mention Zeppelin’s “Cashmere”. Must only work when you’re on drugs, I guess.
Besides that, anything by the Buggles.
Video Killed the Radio Star would kill my mood faster.
I’ve always been told that “Moments in Love” by The Art of Noise was a good one for this sort of thing, although I’ve never used that one personally for just such an occasion (Though I am a REALLY BIG Art of Noise fan).
Personally, I’ve used entire Kenny G Live CD for that occasion. It worked out rather well. 
First, it’s Kashmir, like the state in India. I have found these discs to be great sex soundtrack music.
Philip Glass, Glassworks
Macy Gray, ** The Way Life Is**
Richard Wagner, Mild und Leise, aka the Liebestod from Tristan und Isolde.
Anything by Prince
Pink Floyd, Echoes
Bob Marley, Legend
Anything with a nice repetitive beat to help you get your freak on works.
Ted Nugent’s “Stranglehold”
Nine Inch Nails’ “The Downward Spiral”
“Wicked Game” by Chris Isaac
“Crush” and “Crash” by Dave Mathews Band
“Take my Breath Away” by Berlin
“Let’s Get it On” Marvin Gaye
Jazz (no vocals, unless its Billy Holiday), and classical (but nothing too bombastic - Holtz, for instance, is just too much, same with Mahler), maybe Haydn or Mozart. Bolero works because of the repetition and the looooong build up (a little trite, but good for a laugh).
Speaking of Philip Glass, a joke:
Knock knock
Who’s there?
Philip Glass
Philip Glass who?
Knock knock
Who’s there?
Philip Glass
Philip Glass who?
Knock Knock
ad infinitum (or nauseum)
I put on Barry White once and my (ex) girlfriend was like, “Oh no, we’re not fucking to that.”
She got really mad about 15 minutes later when I started singing along to the CD, right in the middle of sex.
Group in general: Dead Can Dance.
Particular album: Pink Floyd’s “Wish You Were Here”
Particular song: More Human than Human
BT’S ESCM
Certain tracks off of The Jungle Brothers’ V.I.P. album: Sexy Body, Freakin’ You, I Remember. Overall, the CD is pretty good backgroound music for gettin’ freaky.
Al Green.
I Burn and When I’m Away by The Toadies.
Blue Buhdda, by My Life With The Thrill Kill Kult.
I’m a foaming at the mouth Zeppelin fan, so I have to point out that the song title is “Kashmir.”
To answer the question, anything by Van Morrison (esp. Moondance) or Dusty Springfield.
Kinda off the subject–until pretty recently, I thought the lyrics to that song were “Paul Newman” over and over again. I guess that wouold make it a good sex song.
jubei2k –
Your ex has no taste.
Another vote here for Barry White. There’s a guy at work, sounds exactly like him.
Wonder if he’d be amenable to coming over and hanging out under the bed. He could just talk till things got going good. Wouldn’t even matter what he said. Sigh.
Anything with amazing saxaphone. Too many words are a bad thing. I agree with cheepbastid about Enigma. Clannad is pretty good to or Enya. It depends on the sex though. Hard sex needs hard music etc.
I can’t imagine getting it on with Kenny G or classical music. Ick.
However, I recommend:
“Crash” by Dave Matthews
“Supernatural” by Santana
“This is Jazz” Billie Holliday
Anything by John Coltrane
Well, why not the 1812 Overture?
There are only two songs you need for sex:
Wagner’s “Ride of the Valkyries” and Yello’s “Oh Yeah”.
The proper music of intercourse is R&B, like the Clovers, Fats Domino, or Hank Ballard and the Midnighters. Hell, Hank Ballard is practically trying to teach you rhythm:
Oh baby, get it
Get it
Get it, get it, get it.
You know I waaaana
Seeeeee you wit’ it
Wit’ it
Wit’ it, wit’ it, wit’ it
Because I’m yours darling baby
Yours right away…
A lot of your early fifties R&B had a clearly sexual beat.
