Your comment in your last post is on the mark:"I have no problem with the word "soul" as pertaining to music.Just like any other word the meaning depends on how it's used".
Webster's dictionary definition of "soul": "A man's moral and emotional nature, the quality that aroses emotion and sentiment". As used in this context I think most would agree D Brubeck who reached many over decades , had "soul".
Websters also defines
"soul" as " A quality that is essential to or characteristic of the cultural heritage of black americans".
So it is the context and you both are right.
As to your last statement in the post I thank you for your consideration.
Now back to the music:
