I liked the anti-establishment, Anarchist/socialist vibes of the Hardcore punk rock island. Don't like all of the macho posing and shrieking (neither in punk and especially not in the more "black" part); and double dislike the crass commercialization of so much of it.

Punk is for politics and Metal is for Partying.

Yeah very good song choices there.

Anarchist/socialist are such funny words to put a slash between. They seem like such polar opposite political structures

Consult "Homage to Catalonia" by George Orwell. In the Spanish Civil War, Orwell soldiered with anarchists and socialists and the rest of the worker's parties, against the fascists.. until the inevitable purge.

Anarchism has historically been a current within the larger Socialist movement. Socialism is not just establishment sheep-herding rhetoric like Bernie Sanders' or the French Parti Socialiste; nor just the centrlized-state authoritarianism of the USSR. In fact, the labor movement in the US once had more prominent Anarchist leaders than state-socialists - the struggle for the 8-hour workday and May 1st, the Industrial Workers of the World, etc. And there are Anarchist traditions in the workers' movements of Latin America and Europe of course, and to a much lesser extent in Asia early 20th century Asia.
