Generally your taste in musics sets in during your adolescent years.
What were you listening to, driving around late at night after the first one of your friends got their license?
That the type of music you're going to fall back on when you got nothing else to listen to.
And if you're in the metal scene, at least in the early to late 2000s... No part of rap/hip-hop/similar were allowed. No dance music. No pop music. It was the south, so there was some country mixed in that was allowed - old school Willy type shit, the outlaw legends at house parties. Everyone was trying to out-brvtal each other or some stupid shit though.
I got out of the scene because I left that social circle behind after starting a career, but kept a few close friends. They faded over time.
Working nightshift at a hospital does not bode well for your social life. You're at work when everyone else is in the pit drunk off their asses.
I worked alone so I listened to my old shit, and eventually got tired of it. Eminem dropped a surprise album, and I liked some of his stuff (like I also like trance stuff for concentration, like work) and started listening, and I'm a former percussionist so I started drumming along in the air, and realized.... man hip-hop drum grooves are chill, laidd back, flow, get people moving. Fuck yeah. Then I dove deeper. Ended up getting into some underground crap, and I'm still exploring going back to the 2000s stuff that was popular and I heard "around" in the world. I dig some of it too without the egotistical guitar soloists who just want to musically jerk off in front of everyone influencing everyone with their snobby bull shit. Yeah, snobby metal heads exist. Their title is probably "lead" something in the band.
I'd like to go on, that when I was a teenager me and friends split off into pairs as a sniper and spotter, and played war games with each other. Eye pro, tac-vests that held stuff and were just another layer against a pellet, sometimes heavier clothes (winter), but in the summers it was usually dark colored shorts and tees, and a little bush craft (I picked up a surplus army sniper manual).
Dangerous? 110%
Painful? Only if you get spotted.
Dumber than we allowed ourselves to feel at the time? You betcha.
Cutting to the chase, each pair came up with their own sign language that was useful in the dark, in the quiet, etc.
One of our buddies knew ASL (hearing impaired, deaf parents) so they used that.
Me and my partner decided on NATO hand signals, as we were both the most of ware of that format.
The others? Not entirely sure.
I know a lot was just made up on the fly through gesturing and combining the few signals we remembered, and that was all of us except our hearing impaired buddy.
So yes, some sort of sign language is often created on the fly based on cultural parameters. ASL, NATO, etc... just standardizing the symbols helps, but a lot of families, especially without access to resources use "home-sign" as I've heard it called. Basically, they standardized within their family unit over time based on mutual understanding.
So, there are cultural elements, but it expands past that.
I'm older, spent my 20s in a mosh pit fighting to the front, have ND related APD, at least I think, but sound is still HUGELY important for me in the world. Just don't talk to me, lol.
