I like Billyreif's list. Jon Anderson (Yes) and Steve Walsh (Kansas). When they were at the top, nothing could touch their range and vocal ability. Steve Perry from Journey had near perfect pitch.

There's a lot of great vocalists out there and a number of not so great vocalists that have several platinum albums. I don't think anyone in the band Kiss would qualify for the top 20 vocalists. But longevity and sales speak for themselves.

Celine Deion and Barbara Striesand are phenominal. But their music is narrow in appeal.

BOB MARLEY!!!!!! He wasn't really a singer though....he was a God!

i'm picking two that sang together , since thier harmony was some of the best before they went thier seperate way's.

Simon & Garfunkle

Steve Perry -Journey

Freddy Mecury - Queen

Elvis

Wierd AL - best comedy singer i know with out a doubt!

George Straite - for singing country

Loretta Lynn - for country as well

The Rightious Brothers (i believe i spelled it wrong)

but as for best ?? everyones a critic so it's left for you to decide. but top 20's.......we can all pretty much agree on !

Adam Sandler is a way better comedy singer than weird Al Yankovic, IMO.

Annie Lennox

Michael Crawford

Neil Diamond

And for the traditional rock n' roll fans out there

Buddy Holley

Jerry Lee Lewis (hahaha!)

smelly , smelly , smelly ......

Sandler "Over" Weird Al ? .......no contest . weird Al's got him beat just with Amish Paradise !

and i like the "Electric Amish" right behind Wierd Al ! if you haven't heard them ...you should !

The Electric Amish

but to each his own .... i like Adam Sandler as well ! more-so in his movies than in his singing. 🙂

Michael Bolton

Robert Plant

Freddie Murcury

Frank Sinatra

Dionne Warwick

Paul Rodgers

Shirley Bassey

Roy Harper (Hat's off to...)

Hall & Oates

Nancy Sinatra

Cher

Meatloaf

Steven Tyler

Dionne Warwick? Ouch

BOB MARLEY!

A lot of great singers named, and quite a few funny jokes. I guess I will be a majority of 1, since it is all just a matter of taste, your generation, musical background, etc., and say that in her later years, with a range from basso to soprano, the greatest combination of style and voice I ever heard was Sarah Vaughan.
