Using Rage Against the Machine was just stupid. I'm guessing they never listened to any of the words and just went for a beat. Even then it doesn't feel like a beat for old white folks in their 70s and Uncle Toms.
Re-appropriation is the name of the game. These jerks don't really make much art for themselves; a movement 60+ years old really should have an identifiable subculture with its own stuff by now. Instead, they're very good at acting like a bunch of kleptos, running with what they can.
