Help me make my revolutionary/anti-establishment CD

[TrakMastaTom]

I am trying to come up with a bunch of revolutionary/anti-establishment music for a CD or 2. I am open to all genres, but I would prefer if the song were driven by its lyrics. Artists that I already have include:

Rage Against The Machine
Public Enemy
Dead Prez
X-Clan
Street Dogs
The Perceptionists

Any help would be awesome. Reccomend not only artists, but some good songs that display anger towards "the man."
