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'd give a vote for James Taylor. His attention to the music, the harmonies and the quality of recordings also is a plus. He has a silky smooth voice and is a great musician/song writer. He has produced great music for 4 plus decades.
Sam Cooke. Maybe somebody already mentioned him (I enjoyed the thread, but did not have time to read all of it), but he would certainly warrant a repeat reference.
Let's see, how about Jussi Bjorling, Feodor Chaliapin, Roy Orbison, Jackie Wilson, Solomon Burkes, and. . .

for the 21st century: Ronaldo Villazon.
