Jackie Wilson was one of a kind.

Even as a "Gen X'er" myself, my vote for best male and female "singer" goes to Barbara Streisand and Elvis repectively!
I don't even own any of their music per se. Yet, in terms of heart, depth, emotion, substance, talent, skill, vocals, and ability to "move a crowd", I pic those two.
yeah, yeah, yeah, there's a lot of "pretty voices" out there to pic from in all genre's of music. And you might even argue there's better "voices' out there to put in that "pretty sounding" or "greatest voice" category. But as "artists of their craft", I chose Bab's and the King!...even if I don't Barb's political outspokeness.
If I pic "voice" alone, there's simply too many to list!
In fact, we could make a very very long list for both men and women in that category, and still not have a winner
