Chart sensation Taylor Swift is being sued for $42m (£27m) for allegedly stealing the lyrics to her hit song Shake It Off.
US R&B artist Jesse Braham – who goes by the stage name Jesse Graham – has claimed in legal papers that Swift stole the words from a song he wrote in 2013, called Haters Gone Hate.
As well as the possible cash grab, Mr Braham has demanded that his name be added as a writer on the track.
Pennsylvania-born Swift’s representatives have yet to officially comment.
Shake It Off topped music charts around the world and reached the number two spot in the UK. The video for the song has been viewed more than 1.1 billion times on YouTube.
Braham’s lyrics are: “Haters gone hate/players gone play. Watch out for the fakers/they’ll fake you every day.”
Some of the lyrics in Swift’s 2014 hit are: “Cause the players gonna play, play, play, play, play/And the haters gonna hate, hate, hate, hate, hate.”
Apart from the lyrical similarity, the two songs bear no resemblance musically.
Braham says he believed there was “no way” Swift could have penned the lyrics independently of his song.
“Her hook is the same hook as mine,” he told the New York Post. “If I didn’t write the song Haters Gone Hate, there wouldn’t be a song called Shake It Off.”
He added he had spoken to Swift’s record label, Big Machine, four or five times about the issue.
Braham originally asked to be named as a writer and requested a selfie with Swift, but was repeatedly ignored and told his claim had no merit.
“At first I was going to let it go, but this song is my song all the way,” he said.
