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.

Let's see, how about Jussi Bjorling, Feodor Chaliapin, Roy Orbison, Jackie Wilson, Solomon Burkes, and. . .

for the 21st century: Ronaldo Villazon.
What's up! Have we all forgotten Tiny Tim? Does anybody think Sinatra, Caruso, Dylan or any of the above mentioned could have made "Tip Toe Through the Tulips" a smash hit? OK, maybe Dylan.
