Despite its popularity, Taylor Swift’s hit song “Shake It Off” has sparked controversy after a musical trio accused her of plagiarism. Today, the singer’s legal team dismisses their accuser’s experts as unqualified.

According to Billboard, the pop star’s legal team has asked a federal judge to remove the “unqualified” expert witnesses from her upcoming trial.

The lawsuit has been in the works for five years, and Swift finally got the chance to face the court in a jury trial in January.

Swift was accused of stealing the lyrics to her song “Playas Gon’ Play” by the all-female group 3LW.

Even though the “Out of the Woods” singer and her lawyers wanted to drop the case, the judge overseeing it refused to dismiss it.

For the upcoming trial in January, both music acts will rely on expert testimony to make their case compelling to the jury.

Swift’s lawyers, however, stated in a court filing that 3LW’s experts are insufficiently qualified to be included in their case.

They also claimed that one of the experts’ arguments is “unsupported, purely subjective, and irrelevant.”

According to the lawyer, the expert’s deposition testimony “confirms he is simply making it up as he goes along.”

The case has been going on for five years, as the songwriters Sean Hall and Nathan Butler filed it in 2017.

The lyrics in question were “playas, they gonna play, haters, they gonna hate” which they alleged sounded similar to Swift’s “‘Cause the players gonna play, play, play, play, play and the haters gonna hate, hate, hate, hate, hate.”

The team representing the 32-year-old pop star has been attempting to dismiss the lawsuit, claiming that the words “players” and “haters” are too common to be copyrighted.

Swift filed a sworn declaration last month, claiming that she entirely wrote the song and that she had never heard “Playas Gon’ Play” before.

The “Paper Rings” hitmaker explained how the song came to be by drawing inspiration from her life experiences, particularly when dealing with public scrutiny.
