sexiest sounding female vocalists?

I like a somewhat raspy voice, like Melissa Etheridge.

Gotta say though that Christina Aquilera's (SP??) strong pipes are pretty hot.

If only she would sing the blues....

Regards,

I have a list:
1. LHasa
2. LHasa
3. LHasa
4. Jill Seifers.

For Me it's always Been Chrissy Hynde, althought I noticed that nobody has mentioned Brooke Burke (formerly with the Story) or Lady Day herself...

Here's a 6-pack that do it for me:
Hope Sandoval of Mazzy Star
Margo Timmons of Cowboy Junkies
Julee Cruise "Floating into the Night"
Sarah McLachlan
Bonnie Raitt "Give it up"-indeed
Astrud Gilberto "Girl from Ipanema" & "Corcovado"-WOW!

Shirley Manson of Garbage

and Free Dominguez of Kidney Thieves

although, there are a lot of other great suggestions listed above.
