Trent Reznor of Nine Inch Nails demonstrates what all socially conscious artists ought to do. He's released an album with meaninful lyrics, and is giving it away for free. Not only that, he encourages You to remix it and post it on your blog, podcast it, and basically give it away however you see fit, under a Creative Commons license.
I jut downloaded The Slip and was listening to the song Letting You. I didn't catch all the lyrics so I looked them up, and was impressed enough to want to post this...
The sky is painted black
The smoke pours out the stack
One hand upon your heart
One hand behind your back
You train us how to act
You keep the fear intact
The imminent attack
Everything is right on track
And we are letting you get away
We are letting you get away with it
