If you are asking about the best male vocals....no doubt and hands down it is Roy Orbison (many very good singers gave him that distinction when he was alive), Elvis next, and Nat king Cole last... People who aren't into rock I'm sure won't agree but I listen to everything except rap and those three certainly have to be the best....If you should think otherwise, try putting your singers best vocal on and then listen to Roy Orbison's "End Dreams". If you think your singer's vocal is better please E-mail me the song title and I'll buy it....(yes I'm a big opera fan also)
