Josh Groban --- though he wastes it on cheese
Kelly Clarkson -- she can really do anything really well
Derek Webb and his wife Sandra McCracken -- just plain good
Sara Groves -- soft and pretty
Paul McCartney -- though not the best in technical, has the uncanny ability to be perfectly fitting to the music
Billy Joel -- listen to his music over the years, he's so multitalented
Susanna Hoffs -- there's a unique quality to her voice that I just love
James Taylor -- His early stuff before he got kinda lame
And last but not least...
Early Motown vocalists. Usually it's not fair to name a whole label, but for awhile there Motown was pure gold, one great vocalist after another after another. A few became legends, others only had a couple hits, but just about all of them were fantastic. I love classic Motown stuff.
