I agree with your analysis to a degree, but wonder if singing songs with good choruses would also mean that music was thereby limited to simple structures that could be picked up easily. Also, I wonder where such songs would come from, as this is what capitalism has historically been good at.

Maybe a somewhat mangled Frankfurt School type argument, of Second Viennese School vs Tin Pan Alley and "jazz", modified by Bourdieu's analysis of hierarchy of taste?
