Chris Cornell of Soundgarden and Audioslave. I don't actually own any
of their albums, but the Audioslave song "Like a Stone" kinda turns me
on.
YouTube - Audioslave-Like A Stone
I can think of individual songs that I think are sexy, even though I
don't normally listen to the performer, such as:
Lucinda Williams - "Righteously"
KT Tunstall - "Black Horse & The Cherry Tree"
Hole (Courtney Love) - "Doll Parts"
Korn - "Twisted Transistor"
Garbage (Shirley Manson) - "Push It" and "Queer"
Jamie Cullum - "Get Your Way"
Duran Duran - "Rio," "Hungry Like the Wolf," "The Reflex," "Big Thing"
Yeah, I like "Caramel," too. While that one is subtle and sensual, "Blood Makes Noise" is...feverish.
