What song or songs complement Orwell's "Politics and the English Language"

[garthranzz]

and/or the following:

V For Vendetta
"Repent Harlequin, Said the Ticktockman"
Some of The Daily Show's skewering of media complicity or hypocrisy

I've come up with these possibilities:

Revolution
Blowin' in the Wind
The Times They Are A'changing
Give Peace a Chance
Blackbird

(Yeah, I'm dating myself - but I'm looking for songs that are easily recognizable and hit the same 'think for yourself, beware the corporations on one end, the anarchists on the other that matches the other works)
