Is there any research on how music "quality" depends on its popularity?

on The Stand....was a terrible movie, I agree, but a very good novel.
I thought the movie was pretty good for a King adaptation because 90% of his adaptations are abysmal for some reason. (I mean it was pretty bad, but good for him)

Stephen King has always maintained that after he sells the film rights to his books, he doesn't care what they do to the story. I would think that since King has has little to do (Generally) with the film production, the movie suffers.
