Steve Earle, country music's only certified self-described Marxist revolutionary (and a big star for all that) has a disc called The Revolution Starts Now.
It's Amazon sales rank 42,000 +/-, which is pretty good for a 4 year old CD by a second rank artist.
It is twice as a high an Amazon ranking as Lee Greenwood's extremely annoying I'm Proud to Be An American (2007), which comes it at about 81,000.
There, be encouraged.
