There is no best female recording, it means you are willing to sacrifice some of other recordings if you look for best female recordings listed here? While I agree some of here listed are indeed "some" of the best, but it just impossible to list them all, I like to go by tracks instead of female artists alone, it’s hard to compare which is the best, each unique in a way that you are not going give up listen to.
My first impression of female voice from Whitney Houston, it came out of radios, though that time when I was child, the time back then was start of 90s, I would say that her voice is not as soulful as Aretha Franklin or Nina Simone, but her voice is kinda unique in it’s own, both technically and emotionally, she kinda create more "well known" recording or live ballads than anybody else, these singers are not much considered as "clean" audiophile", as they sing on the go soulful way as opposed to the likes like Norah Jones, Diana Krall, Eva Cassidy, and Katie Melua which I think few tracks like Piece By Piece & Nine Million Bicycles are indeed nice, but some of other Katie’s tracks maybe too young in her presentations, the 3 former white Jazz singers are very well known to audiophiles I assume, here are some of my favourites:

I am not able to list them all I guess, so conclusion there is no best female recordings for me, hmm if got one I would choose Whitney Houston - I Will Always Love You, I’m still finding a version as opposed to the market album recording, the sound is more lively, not sure is it some Dolby Digital sound effect on it
