Best female vocal recording on CD?

i am a sucker for great warm rich smooth female vocalists, especially on tube gear and speakers that image well. but i am almost always faced with a great voice/song but a sonically inferior recording (examples too numerous to list) or a great recording of a mediocre voice.  rickie lee jones (pop pop) comes to mind- fab recording, but come on lets be honest about her voice. however, i will almost always pick great recordings and leave the bad recordings for the car.

 so i am asking for what you use as a reference female vocal recording/track. right now i come back tp bonnie raitt "you cant make me love you" from luck of the draw.  big, warm, strong voice. not a perfect recording. but hmmmm that voice.

my only requirement is it has to be on CD. and we all know of great vinyl that did not translate into great CDs.  so help me out here, what should be my next music purchase 
I found recently a newish female singer playing on Mark Knopflers new album Tracker her names Ruth Moody she has a couple of her own albums out as well she is quite lovely.

Anita Baker CD My Everything

Sade CD The Best Of

Joe Sample featuring Lalah Hathaway CD The Song Lives On

Joss Stone CD The Soul Sessions

Aretha Franklin CD So Damn Happy

Randy Crawford & Joe Sample CD Feeling Good

These CD's are all well recorded. Vocals are superb!

@glennewdick -- good pick with Ruth Moody

Check out her work with the Wailin' Jennys (this is "Arlington" from "40 days")

And while your at it try Heather Masse (another member of the Jennys) with Dick Hyman
