Hmmm. Well, the Pink Floyd considered best for the bedroom (Meddle) is also the most ambient Pink Floyd album.
As for me, I always say, Sexytime is Billy Idol time!
OK, more seriously now...
I remember at the first live performance by Viridian Sun, a girl in the audience came up to the stage afterward, when we were taking down our equipment, and said "I just wanted to tell you, your album is SOOO great to make love to." Wow.
I guess I would say, without giving away too much of The Griffin Technique, that more dynamic albums with more variety and change, would be more suitable for this sort of thing, than the more minimal or drony stuff. But everything can have its place!
