Question: Taylor Swiftâs lawyers  are trying to shake off claims that the âShake It Offâ singer stole lyrics with a new court motion.
 Swift  was sued in September by songwriters Sean Hall and Nathan Butler  who created the song âPlayas Gonâ Playâ for the girl group 3LW in 2001. The duo claimed that  Swift  stole their lyrics and used them in her famous hit single âShake It Off.â
On Wednesday  the singerâs lawyers asked the federal judge to dismiss the copyright lawsuit against  Swift  and argued that the concepts of players playing and haters hating are common music phrases and âpublic domain clichÃ©sâ that canât be claimed as copyright  according to Variety.
 Swift  used the familiar phrase in the chorus of her song which says  âPlayers gonna play  play  play  play  play  and haters gonna hate  hate  hate  hate  hate.â
âThere can be no copyright protection in âplayas  they gonna play and haters  they gonna hate â because it would impermissibly monopolize the idea that players will play and haters will hate â  Swift âs lawyers said. âPlaintiffsâ claim to being the only ones in the world who can refer to players playing and haters hating is frivolousâ¦ Providing a copyright monopoly in the phrase would prevent others from sharing the idea that players play and haters hate.â
To further prove their argument   Swift âs legal team went on to cite other examples of famous songs that use the âplayerâ and âhaterâ phrase such as âDreamsâ by Fleetwood Mac  in which the song says  âPlayers only love you when theyâre playing â and âPlaya Hater â by the Notorious B.I.G.  where the phrase âplaya  playa haterâ is used as the part of the songâs chorus.

Answer: Taylor Swift
