There seems to be some tendency on the part of music professionals to see the "audience" as an amorphous group needed mostly to keep them in a job. I think any performer can tell you a story of other performers dismissing the knowledge or taste of an audience (and other musicians!). The term may have gone out of style now, but a few decades ago some music was called schmaltzy, and anyone who liked it was some kind of rube. Then there's the whole épater le bourgeoisie thing that still has its adherents.
It seems to me the answer is not one kind of music, but offering lots of different kinds of music and styles of performance to appeal to the various audiences out there not being served.
