Distinct Voices

I am currently listening to Kings of Leon. I love their songs! And I love the vocals. Which made me realize that I am drawn to interesting vocals. I can't really describe it, but there is just something about them that makes me really listen (usually with tingles going down my spine).

Here are a few that can do that:
Paul McCartney
Brandon Boyd (Incubus)
John Legend
Patrick Stump (Fall Out Boy)
Frank Sinatra
Josh Turner
Clarence Greenwood (Citizen Cope)

Those are the ones that I can think of at the top of my head. I notice that they are all guys...Wonder what that means?

What are your favorites?
