But people like them, no? Just to be clear, how people can enjoy autotuned mumbling about money and hookers is beyond me, but they are. Don't know about other genres, but in metal you still have a lot of bands that make complex and beautiful music (especially in symphonic metal), but not as many people listen to that, and often not because they don't know about alternatives. My own brother listens to mumble rap and other rappers that write lyrics that can be rearranged and you wouldn't notice because the only thing they do is rhyme, without building up to anything, and it's his choice, he likes listening to the same two songs in 50 variants.

It is very easy to find smaller bands that produce music with actual effort, and you can shove crappy music all you want to someone who doesn't like it, and it won't magically make them a fan, so the prevalence of autotuned simulations of strokes are due to people actually liking them, no?

I try not to judge these people too much because I myself often listen to extreme trve kvlt black metal which sounds like a vacuum cleaner to the uninitiated, so I tell myself that it's something like that. I never convince myself of that, but I try.
