Best CDs for vocals?

I'd add to the list:
Jennifer Warnes - "Famous Blue Raincoat" & "The Well"
Holly Cole: "Temptation"
Bonnie Raitt: "Luck of the Draw"
Eva Cassidy: "Songbird"
Etta James: "Life, Love & the Blues"
Mark Knopfler: "Golden Heart" & "Shangri La"
Dixie Chicks: "Home"
Chris Thomas King: "Me, My Guitar & the Blues"
Runaway Express: "Oh, Boy" (local Denver band does Buddy
Holly stuff really well; check their web site)
Ray Charles: "Genius Loves Company"

That should get you started.

thanks for all the options :) I hope to buy several of these in the next couple of weeks.
