Representatives for Taylor Swift have rejected a copyright infringement lawsuit filed on Monday by two songwriters over Swift's hit song Shake It Off as a "ridiculous claim."
Songwriters Sean Hall and Nathan Butler said in a lawsuit filed in U.S. federal court in Los Angeles that Swift's song used the phrase "players, they gonna play, and haters, they gonna hate," that they had coined for a 2001 song Playas Gon' Play by R&B girl group 3LW.
Swift's lyric from her 2014 hit Shake It Off is: "the players gonna play, play, play, play, play, and the haters gonna hate, hate, hate, hate, hate."

Swift recently released details of her new album Reputation 

"This is a ridiculous claim and nothing more than a money grab," the singer's representatives said in a statement. "The law is simple and clear. They do not have a case."
Hall and Butler are seeking unspecified damages and a jury trial.          

Hall, a songwriter and producer for artists such as Justin Bieber and Maroon 5, and Butler, who has worked with artists such as Backstreet Boys and Luther Vandross, claimed that the combination of playas or players with hatas or haters was unique to its use in 3LW's Playas Gon' Play.
"In 2001 it was completely original and unique. Indeed, the combination had not been used in popular culture prior," thel awsuit said.

Swift was recently won a court battle against a US DJ

Hall and Butler said the phrase accounts for about 20% of the lyrics of Shake It Off. They claimed that Swift and her team "undoubtedly had access to Playas Gon' Play before writing and releasing her song.
"Defendant Swift has admitted that she watched MTV's TRL which promoted Playas Gon' Play, the lawsuit said.
It said Playas Gon' Play debuted at No. 7 on MTV's Total Request Live in March 2001 and that 3LW's debut album sold more than one million copies.
