Rapper Rick Ross is hoping to end Lmfao’s party rocking days after filing a copyright infringement suit against the colourful pop duo over its use of the phrase “Everyday I’m shufflin’”.

Ross claims the line from LMFAO’s smash-hit Party Rock Anthem is an illegal “derivative” of his phrase “Everyday I’m hustlin’” from his 2006 debut single.

In documents filed in Florida, the rapper insists, “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 (sic) derivative work.”

He also claims the the phrase is performed in a manner to sound just like him and is therefore “an obvious attempt to capitalize on the fame and success of Hustlin’.”

Ross is seeking an injunction and maximum statutory damages.
