Last year’s 1989 has spawned several huge hits for Taylor Swift, but no one will be forgetting the project’s lead single “Shake It Off.” The carefree track won its way into the hearts of many with its addictive melody and quirky dance video. Hailed as the beginning of a new era, the single debuted atop the Billboard Hot 100 and has become an instant fan favorite.

While many have accredited the single’s success to Taylor Swift and her team, musician Jesse Graham thinks otherwise. According to him, the musician stole lyrics from his 2013 ditty “Haters Gonna Hate,” and he is suing Swift and company for $42 million in damages.

The lyrics in question are “haters gonna hate / players gonna play,” which Swift sings with gusto on her song’s hook. Graham’s track is markedly different in terms of production and overall aesthetic; however, he claims that his song was obviously the driving influence behind Swift’s. Obviously.

“Her hook is the same as mine,” Graham insisted in an interview with the New York Daily News. He went on to claim that, “if I didn’t write the song, there wouldn’t be a song called ‘Shake It off.’” Although he originally decided to leave well enough alone, Graham claims that he couldn’t allow Taylor Swift to profit off his song. “At first I was going to let it go, but this song is my song all the way,” he vows. Yeah, good luck with that case, buddy…

Graham claims that he would be content to be credited as a songwriter on Swift’s single, but that her team refused his request. They, like just about everyone else in the world, don’t believe that Graham’s claims have any merit. The refusal has been taken as evidence that Swift and her team are “trolling” him.

For what it’s worth, we think that Jesse Graham’s claim is pretty bogus. Maybe Mariah Carey should swoop in, since the song shares a title with her 2005 single? Maybe anyone and everyone should sweep in since the phrase “haters gonna hate” is pretty common. Neither Taylor Swift not Jesse Graham pioneered the phrase, so trying to claim ownership of it is pretty silly. Best of luck though…
