Fans of LMFAO's "Party Rock Anthem" had the entire world shufflin' back in 2010, but now Rick Ross is trying to take down the catchy tune, suing over copyright infringement. According to The Hollywood Reporter, Rick is suing over the phrase "Everyday I'm shufflin'," claiming the lyric is too derivative of his lyric from his 2006 hit "Hustlin'."

If you're still scratching your head over this crazy case, you're not alone. Rick claims "Everyday I'm shufflin'" is too similar to his lyric "Everyday I'm hustlin'." Um, since when was rhyming a violation of copyright?

"The use of 'Hustlin'' in 'Party Rock Anthem' is readily apparent, despite the slight change from 'Everyday I'm hustlin'' … to 'Everyday I'm shufflin'' … and constitutes, inter alia, the creation of an unauthorized derivative work," the Florida federal court lawsuit reads. Hmm, interesting.

Not only are LMFAO, made up of Stefan Kendal Gordy (Redfoo) and Skyler Austen Gordy (SkyBlu), being sued for the lyrics, but they're also getting heat because the phrase is "performed in a manner to sound like" Rick's song and "is an obvious attempt to capitalize on the fame and success of "Hustlin'."

Given the fact that the massive success of LMFAO's song has led to the song appearing in many TV shows, movies, video games, and advertisements — not to mention their Party Rock Clothing line — Rick is looking for his piece of the "Party Rock Anthem" pie.
