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.

Hmmmm....How about some votes for uniqueness of voice with regard to this topic:

Tom Waits
Peter Gabriel
Richard Butler (Psychedelic Furs)

CD
Coolest guy of all time: (ALWAYS GOT THE HOT CHICKS)

The King

For rock and roll all time: Robert Plant
For soul: Marvin Gaye
For heavy metal current: The guy from Disturbed
(Their new DVD-A is pretty impressive)
So many good ones but Gino Vannelli is one of my favorites who is "do" for a brand new album of opera type compositions!
