Yeah, Portishead and Massive Attack (Mezzanine) have been great in the past. Explosions in the Sky is also good (no lyrics, long dreamy tracks), Iron & Wine... try The Stooges' "Dirt" for some good times, and Zeppelin's "Since I've Been Loving You."

Just wanted to thank all the contributors - I intend to download some of the suggested songs. I noticed very little foreign music represented. I dated an Indian girl years ago and we used to listen to Llewellyn's "Tantric Sexuality". 54 minutes of continuous music that was the perfect complement to our lovemaking. Hit the "repeat" button the CD player and enjoy. Luther, Barry, Marvin and the usual suspects from the R&B family will help you into bed, but Llewellyn will take you to another world.
