There are "genre novels" and "genre films". Is there "genre music"?

Back in the days of peak dubstep there were whole ongoing forum threads arguing about what did and what didn't count as dubstep. I think the main thing was that it almost unequivocally had to be at 140bpm or people got aggy

These are good examples of "genre music" in the sense of music that conforms closely to genre tropes. But they're missing the second thing I had in mind, the critical disreputability.

fwiw I don't think it's true in the least to say that genre fiction or genre films are critically disreputable in 2021, we've had decades of tastemakers reassessing these and the "critical disreputability" thing is at this point more of a historical leftover from the days when there were far fewer critics and much more of a monoculture around what "quality" means.

So to that point, all popular music is genre music because the non-genre stuff within that mindset is classical music.

ASC put out an album and two EPs last year where the whole thinking behind them was "I Am Now Making 90s Drum 'n' Bass." I bought them; they were very good.

I'm reminded of a thought I had about how some artists are mercurial and follow their own paths as self invention. But leave recognisable landmarks along the way.But there are lesser artists who see the value of that particular nexus and spend their careers investigating what the possibilities of that particular point are or develop their own sense of self invention based in it.
It was something I inferred about general human interface from reading a good book about tghe development of computer interface The inmates are running the asylum by Alan Cooper though it may have occurred to me independently before that.
