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.

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!
Dennis the menace, Thanks for mentioning Stevie Wonder...another favorite of mine
I agree with Lbietz2001 about Josh Groban. His voice is nearly unbelieveable, especially for someone so young (20, maybe 21 now)...but he's a figure from the 21st Century. My nominees from the 20th Century would include Jose Cura and Carlo Bergonzi for opera; Dean Martin, Harry Connick, Perry Como for pop: Lionel Ritchie and Smokey Robinson for soft rock.
