Best male and female singing voices

You're allowed more than one each gender as music is like that, I dont like how non musos have to rank people as that's not how music works. However, a few of each, each:
For me
male: Sam Cooke, Otis Redding, Art Gurfunkel, Frank Sinatra
female: Norah Jones, Ella Fitzgerald, Stevie Nicks, Dusty Springfield

anyone else?
