This is juvenile...

Aimee Mann (songs)
Amel Larrieux (Looks and vox)
Adriana Evans (Looks, also jazz singer Mary Stallings little girl)
Rachel Z (musicianship.and when she was a bit younger - (Just call me Shallow Hal)
Sade (booty..WHAT???)
(You guys have all my other picks).

Norah Jones is pretty laid back , attractive,and seems pretty 
mild mannered . Everyone likes something with different twist.

Juvenile indeed, but

Yuja Wang

(plus Hilary Hahn, plus Julia Fischer)

@grannyring -  Can we share?

@audioman58---Apparently Keith Richards finds Norah very attractive. The two of them did a duet on "Love Hurts" at the tribute show to Gram Parsons at The Universal Amphitheater in 2004. I was in attendance, and watched in horror as Keith couldn't keep his hands off her---he was all over her. It was creepy---he was acting quite lasciviously, and she looked very embarrassed. I was embarrassed for him. Keith, dude, act your age, not your IQ.
