As a 50 something American itching for a revolution, Volunteers by Jefferson Airplane really speaks to me.
Well, there is always Queensryche's song Revolution Calling. It's a good hard rock song with some interesting lyrics, but these guys bordered on being communists if they weren't out and out Marxist/Leninist.
I've always found it pathetic these far left entertainers making gobs of money thanks to capitalism while doing everything they can to undermine the very system that is making them rich.
