Best Male Singers of the 20th Century


There is an interesting current discussion about the best female vocalists on CD. I have my own ideas about the best male singers (any category) of the 20th Century, but would like to hear other opinions.

I think that Frank Sinatra is the greatest male singer of any century. Long live his music.
I imagine Mr. Sinatra will have a comanding lead here. But (probaly intentionally) no category was mentioned. What about clasical (opera) singers? Anyone want to discuss Enrico Caruso vs. ?. What about comparing record sales? Is Elvis Pressly a contender because of volume of his record sales? Personally, I really like the jazz singer Johnny Hammond, especially his album with John Coltrane. Chet Baker, while I wouldn't EVER classify him as a great singer, had a distinctive way with singing jazz that was certainly unique, and very emotional. In sum, besides Hammond, I guess Francis Albert is the winner.
Well, I am sure someone will mention Belafonte, and of course there is Nat King Cole (the DCC reissues are awesome) In the "sub class" of Best singer/songwriter, I'd vote for Jacques Brel also.
