 While it's true no single song has yet to emerge as the Occupy movement's anthem, there are clearly plenty of songs, from all different genres, that express the movement's frustration with the 1%.  Given the incredibly broad range of musical tastes nowadays, that may be just fine.

Good example:  Here's a contemporary track from the garage rock genre, a new recording of the fist-shaking 60's protest / garage rock anthem "NOTHING CAN CHANGE THE SHAPE OF THINGS TO COME": http://tinyurl.com/7p93vvm

The lyrics are just too relevant:
 
"There's a new sun rising up angry in the sky.
There's a new voice crying but not afraid to die.
Let the old world make believe it's blind and deaf and dumb
BUT NOTHING CAN CHANGE THE SHAPE OF THINGS TO COME.

There are changes lying ahead on every road.
There are new thoughts ready and waiting to explode.
When tomorrow is today, the bells will toll for some.
BUT NOTHING CAN CHANGE THE SHAPE OF THINGS TO COME.

The future's coming on sweet and strong,
And no-one's gonna hold it back for long...

There are new dreams crowding out old realities.
There's revolution sweeping in like a fresh new breeze.
Let the old world make believe it's blind and deaf and dumb,
BUT NOTHING CAN CHANGE THE SHAPE OF THINGS TO COME. "

(BTW, the whole album is pretty decent, if you are into that vintage 60s garage rock thing.  It's a free download http://tinyurl.com/7od26by)


Thee Dirtybeats - Nothing Can Change The Shape of Things To Come (from 2011 ep "thee dirtybeats" http://www.theedirtybeats.com)

Chapel Hill NC's THEE DIRTYBEATS (http://tinyurl.com/7od26by) specialize in recreating the tough, primitive, aggressive vibe of early to mid-60s garage rock and psychedelia -- the sound that inspired proto-punk pioneers like MC5 and The Stooges.

To get that sound, THEE DIRTYBEATS uses period gear, including vintage KAPA, Mosrite, Rickenbacker and Fender guitars, Fender and Ampeg amps, Big Muff fuzzes, Morley wahs -- even coiled guitar cords. The result is prickly, gritty, unpredictable... and (if you are into that pure vintage garage rock thing), utterly glorious.
