Do you ever wonder?

Do you ever wonder why some artists (individuals or groups) attain success through critical acclaim and/or record (cd) sales?

Here is my list of those who have made it in the recording/entertainment industries and is completely puzzling to me.

Please list your own; it's irrelevant what you think of mine.

OK, here you go (in no particular order):

Sheryl Crow
Norah Jones
Michael Bolton
Celine Dion
Joe Cocker
Manhattan Transfer
Boston
Rickie Lee Jones
Pink
Phil Collins

That's enough to get started; show me what you got.
