In general, I like these ideas, but applied to the layperson. For me I've always found that in punk-adjacent music.
In my late teens I discovered that "screamo" was a real genre, and not just a term to describe music with screaming. Emo, post-hardcode, hardcore, math rock all coming together with low barrier to entry DIY ethics.
In that scene the spectrum of what is acceptable is more broad than any I've seen. Some very gear-head oriented, metal influenced, some very primitive, some very melodic, some very rhythmic and angular. And somehow it all made sense to play together because we were united under the only thing that mattered - feelings, typically sad ones 🙂
Other punk scenes exist which similar inclusivity & open-mindedness.
That's where I want to stay, with the rest of people united on a shared meta-goal.
