They don’t make music anymore (broad generalization, I know, but maybe you know what I mean). We’re stuck listening to the music of the 1920s through 1970s, mostly. Then there’s classical music, real music.
Music is still made but the genre classification is so much hairsplitting (and at that point the sounds are redundant) that any concept of “marketplace” has been fragmented into nothingness.
The common culture is gone. So be it.
