On this track, Fergie links up with American rapper Q Tip and producer GoonRock, the man behind many of LMFAO's hits. The Black Eyed Peas' lead singer scats her way through the song, which combines 1920s jazz-style rhythms with contemporary house beats. The song was recorded for the Great Gatsby soundtrack and references the lavish parties held by Gatsby that are described in the novel.
"It's the End of the World As We Know It (And I Feel Fine)" was inspired by a dream where Michael Stipe conjured up images of people with the initials L.B.: Lester Bangs, Leonid Breshnev, Lenny Bruce and Leonard Bernstein.
Ronnie Dunn wrote "Boot Scootin' Boogie" before he teamed up with Kix Brooks to form Brooks & Dunn. It was originally recorded by the country group Asleep At The Wheel, but Brooks & Dunn did it themselves when it got its own line dance.
