It's a match made in battle-rap heaven! On this single from Minaj's upcoming debut, two motormouths – both of whom know their way around a punch line, love goofy voices and suffer from severe cases of multiple personality disorder — team up for nearly five minutes of back-and-forth word-hurling. They rhyme like they're playing hot potato with a live grenade, and Swizz Beatz's hushed, chugging production throws the microphone viciousness into jarring relief. The common theme is anger toward female haters: Minaj tears into a "has-been" femcee who needs to "hang it up" (presumably Lil' Kim, with whom she's been beefing for months). Eminem, meanwhile, rails against a woman who may be a metaphor for life itself. It's hard to say exactly why he's so mad at her — but he threatens to pee on her. Twice.

“(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."
