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.

Only able to comment rock, but obviously people need to listen to Glenn Hughes. How can you compare without hearing? Of course this is all subjective isn't it??
I am truly happy to see that people appreciate Gino Vannelli. I have been following his career and enjoying his incredible music and talent for 27 years!
