NPR's Best Voices

NPR wants its listeners to chip in with their picks for best Voices in Music history. They plan on putting a Top 50 together. I'm not expecting too many surprises. Rolling Stone did one of these years ago.
My own list would include Elvis Presley, Sam Cooke, Paul McCartney, John Lennon, Rod Stewart, Ray CharlesElla Fitzgerald, Billie Holiday, George Jones, Merle Haggard, Hank Williams Sr., etc., etc. I think all but Haggard and Stewart will get on the NPR one.
