Ha ha ha, what a topic!
 I think I would have to either go with Linda Ronstadt or Nora Jones;  nowt that they are the most attractive, but they are, or were, beautiful women with beautiful voices that bring out emotion in me.
This of course also presumed that Marilyn Monroe singing “happy birthday Mr. president” to JFK, does not count as qualifying her as a female vocalist. 

Wow this is very important ill get back to you asap!!!

Susan Tedeschi?
Is she cool enough..? 
If not I will drop her like a hot brick or whatever but....no, I really like her. 
So it's Susan Tedeschi....or Linda Ronstadt circa 1974 but I was a little young so....Susan or Linda or Joni around 1971 but that's it.....unless of course I can include Ann OR Nancy Wilson late '70s and that's IT!! 

OK Diana K is hot and love her music but I can't compete with Elvis (for now....) so maybe Diana Ross around 1972?? Well of course I'm ignoring Michelle Phillips and Janis Joplin (OK just seein if you're paying attention w/JJ....) but maybe Shelby Lynn...AND her sister? Please!!!?? 

OK I'm just a whore. Give me Brandi Carlisle, Carol King, a young Chaka Khan, Edie Brickell, Cher, Duffy, Norah Jones Hell I'll take just about anyone....

.....sorry Madonna, I said JUST about anyone, you can sit your nasty @$$ right back down!!! (I'm saving myself for Kacey Musgraves...)
