"We're money-hungry wolves and we down to eat the rich," Killer Mike warns, sounding at once like a trap-rap hustler and an Occupy anarchist. This Dirty South fixture has evolved into the Noam Chomsky of the strip club, and his sixth LP is his best blast of down-home invective yet, especially when he takes down societal ills from the inside – as on the slow-rolling meditation on police violence, "Anywhere but Here." Some of his punditry is pure Che T-shirt prattle, but even when he's arguing that there's no difference between Reagan and Obama, his Ice Cube-style bark tumbles down over harried, aggro beats from indie-eminence El-P and hits like a gut punch of revealed wisdom.

“(We're Not) The Jet Set”

George Jones and Tammy Wynette were still married when they recorded the tongue-in-cheek "(We're Not) The Jet Set." The lyrics, written by Nashville songwriter Bobby Braddock, who also penned Wynette's "D-I-V-O-R-C-E" and Jones' "He Stopped Loving Her Today," make fun of the good life by declaring, "We're not the Jet Set/We're the old Chevrolet set." Braddock recalled that while writing the song, he needed the name of a city that evened out the rhyme he had with "Riviera" and "Missourah." “I got out a Rand McNally atlas," he said. "In the first part are the maps. The last part is an alphabetical listing of cities. I wanted a rustic, small-time sound. I went to the listing for Missouri. And I found 'Festus.' I loved the sound of it."
