Party Rock Anthem

This club banger is a single by the Los Angeles Electro-Hop duo LMFAO. The song was released on January 25, 2011 via Interscope Records. The song spotlights shuffling, which LMFAO's Redfoo told Billboard magazine is part of Sorry For Party Rocking's focus on dance in general. "Before we just kind of partied and had some personal moves," he noted, "but now there's dances that are out there that people are doing and shuffling is one that really caught my eye and it felt so good when I was doing it, so we just kind of made that song about shuffling."

The track features singer Lauren Bennett from the international girl group Paradiso Girls and newcomer GoonRock. LMFAO previously did a remix for GoonRock's track "We Came Here to Party." The English-born Bennett took part in the UK version of X Factor back in 2006 as part of a duo called Fusion who were dropped at the Boot Camp stage. Her connection with the party rock movement stems from her association with Paradiso Girls, an ill-fated attempt by Jimmy Iovine to create a European spin–off of his other girl group The Pussycat Dolls.

According to Redfoo, the original chorus lyrics were, "I feel it in my soul tonight, everybody's gonna have a good time." Redfoo is the son of Motown founder Berry Gordy, so he knows that getting a lyric just right can make a huge difference in a song, something he may have learn in his time hanging out with Smokey Robinson. Thinking of the song as something you'd hear when you walk into a party, he changed the lyric to "Party rock is in the house tonight, everybody just have a good time." "The 'Just' was key," said Redfoo. "I made it a command, to focus people on what to do now that we're here together. Our lyrics are very calculated, even if they appear simple."
