This is exactly it; when the argument to taste comes in, or the argument it's none but subjective.
There is what I consider absolutely great music I don't actually enjoy most, or even _any_ of the time.
There is music heard around here and in like naborhoods which is literally infantile as far as its tunes go.
There is music that has next-to-no content in it and the tiny bits are repeated over and over with no hope. It doesn't matter if the creator of it is 4 or 60. This is nothing to do with 'correctness', that's a garbage term here anyway. I do all kind of things in music somebody is going to call incorrect; correct, whatever that is taken to be is no guarantee there's anything at all to care about, anyway.
At any rate, at least I'm not being cynical and doing as little as possible knowing somebody is going to buy it because the stupidity of a certain type of person is guaranteed in the world.
There are reasons to care about quality.
