Average artwork has always been garbage throughout human history. But I still found a few good paintings to hang on my walls. As long as you can get what you want it doesn't really matter what else is out there.
Is there a trick I'm missing to avoid this in {Ubers, grocery stores, bars, ...}? If so I'd love to know about it! Note: am blind, so can't constantly wear earplugs.
Or maybe, instead of devolving into absurdity we can just say that there are come qualities of being better or worse that most people can agree on.
Of course, you can simply bite the bullet and say "yep. The song with 1 note in it is subjectively just as good".
Maybe, but enough people like modern day pop music, so by that criteria it is good.
If people preferred more complicated music, then more complicated music would be popular and more of it would get made.
