From https://promusicianhub.com/what-is-punk-music/
In its most basic definition, Punk music is a manifestation of the rebellious, anti-authority punk subculture that peaked in the second half of the 1970s, primarily in the US and the UK. Not just a music genre, but punk is more of an attitude, a philosophy, and a whole way of being.
Sure it doesn't sound like punk music, but they sure as hell ripped a massive middle finger at authority.
I blame the internet, my generation was pissed off and we were going to change things.
Then as we got old enough to actually do something, the internet took off and everyone just started screaming into the void instead.
