Chris Willman Senior Music Writer and Chief Music CriticTaylor Swift clearly believes she’s being played in court, as a declaration she filed to the judge in a “Shake It Off” plagiarism lawsuit laid out her contention that she never heard the song she’s accused of lifting, “Playas Gon’ Play,” until after she was made aware of the legal action.“The lyrics to ‘Shake It Off’ were written entirely by me,” Swift said in paperwork filed in response to the allegation from two songwriters that her 2014 smash infringed upon a single from the group 3LW that peaked at No. 81 on the Billboard Hot 100 in 2001.“Until learning about Plaintiffs’ claim in 2017, I had never heard the song ‘Playas Gon’ Play’ and had never heard of that song or the group 3LW,” Swift wrote in a filing first reported on by Billboard.
