I took your post as "who do you consider the most beautiful female singer?"...
My vote is for Leah Song of Rising Appalachia. She's infinitely talented, a natural beauty, and just has a super cool personality. She is the embodiment of everything wonderful, positive, and creative about indie music.

Leah Song (Rising Appalachia) - Love Stays
Runner up - Cat Power. Wow, what a voice. Sultry, powerful, and beautiful.

Cat Power - Sea of Love (acoustic)
And the most beautiful female singer of all time (IMHO, of course)... Sade. There is no other woman that comes close to her hypnotic beauty, grace, and sensuality. Her voice (not to mention her looks) instantly put me in the mood. She is an icon.

Started off being methodical and consulting the billboard top 20 charts, but ended up elaborating a bit too much
Pop
Taylor Swift – love that little chipmunk teeth thing she has – definitely anal then COT (cum on teeth)
Demi Lovato – camp counselor to bad girl, nice - gag reflex? What gag reflex?
Selena Gomez – Spring Breakers, Beiber’s ex – yup bondage it is.
Hailey Steinfeld – Pitch Perfect 2 (aweful movie) – but a dead ringer for Bella @ Sunnys
Country
Carrie Underwood – glaze that American Idol’s face like a Krispy Kreme (sung to the tune of “before he cheats”)
R&B
Rihanna – yeah man, a little bit of island exotic - bitch better have my money or there will be some disturbia
Rock
Slim pickins here
Current, but not currently in the charts
Ellie Goulding – saw her singing “lights” on SNL – tight dress and cute lisp, seriously fap-tastic
Arianna Grande – serious Daddy fetish here - too many thoughts in my mind.
Katy Perry – because…tits...and....roar.
Shakira, Shakira, Shakira – because...Hips.Dont.Lie
Brittney Spears - Mickey Mouse club, Toxic, Baby. Baby – trailer trash and serious bragging rights. She’d be licking my ass before I could say “y'all wanna fuck or what?”
Cheryl Cole – Brittish. Gorgeous. Great Ass
Miley Cyrus – I am going for Hannah Montana look rather than wrecking ball. However, I’d expect to be “worn-the-fuck-out.” AND she’d put pictures on Instagram
Kelly Clarkson – Original American Idol and now that shes really porky, she’ll have some self esteem issues (kidding..but not really)
Shania Twain AND Faith Hill – many a late night jerk-off session to CMT could never decide which I’d rather have – so have to go for a threesome to see which would be skankier. Lots of ATM combos in my mind and cant decide which one jerks me off over the others face.
Pixie Lott – English blonde chick – innocent and skanky in equal measures
Katherine McPhee – another American idol – lost a ton of weight, gorgeous eyes and DSLs
Fiona Apple – more Daddy fetish
Christina Aguillera – Xtina !!! I imagine her singing some of those incredible runs when getting banged
Old School
Madonna – hold on for that ride
Lady Gaga – never fucked a tranny before
Cher – Ha just kidding ! (But seriously, Id fuck her just to say I had)
Jessica Simpson – probably would be serious and brutal BDSM sex, just because she is so fucking awful
Gwen Stefani – because ….Abs.
Belinda Carlisle – 80s crush, lost a ton of weight and was super hot.
Stevie Nicks – old old school, I imagine her to be super freaky. Plus..coke…weed…shrooms…and lots of pubic hair.
Finally,
Karen Carpenter – the ultimate spinner AND your dick looks enormous (Too soon?
