sexiest sounding female vocalists?

ok what's your thoughts regarding the sexiest sounding female vocalist out there? Just discovered Diana Krall guess the picture on the cover of the look of love may have contributed to my feelings somewhat also.
Okay- Aimee Mann. I likey.
MINNIE RIPPERTON.May she rest in PEACE.Blows away MARIAH...Cant forget the Queen of soul ARETHA.
My vote goes to Astrud Gilberto
Sexiest vocals is Christina Amphlett of "DIVINYLS", self-titled CD with the song "I Touch Myself". Her phrasing and breathing techniques make her sound as if she's having multiple orgasms throughout the whole album!

Best female vocalist is Annie Haslam of "RENAISSANCE".

I also think that Rachel Sweet has a pretty sexy voice as well!
