Taylor Swift might be known for penning emotional ballads and chart-topping anthems, but did you know she quietly co-wrote a global EDM smash — and didn’t even want credit for it?
Back in 2016, when Rihanna’s infectious banger “This Is What You Came For” took over airwaves, most fans had no clue that Taylor was the real lyrical mastermind behind it. The song was officially credited to Calvin Harris and a mysterious co-writer named Nils Sjöberg — but surprise, that name was just a secret alias Swift used to keep her identity under wraps.
Why the Alias?
At the time, Taylor was dating Harris, and the two wanted to keep their professional work out of the spotlight. According to TMZ, she recorded a demo of the song on her iPhone piano and sent it to Harris — who loved it. The decision to use a pseudonym wasn’t shady; it was all about letting the musicshine without being overshadowed by their high-profile romance.
But things took a turn when Harris casually told Ryan Seacrest he couldn’t see himself collaborating with Taylor. That comment didn’t sit well with her camp — and it triggered the big reveal: Nils Sjöberg was, in fact, Taylor Swift.
Calvin’s Clapback
After Taylor’s rep confirmed the news, Calvin first praised her as an “amazing lyric writer” — but then went full savage mode on social media. In a now-deleted rant, he accused her of trying to “tear [him] down” and dragged her rumored fling with Tom Hiddleston into the drama. He even threw Katy Perryinto the mix, referencing Swift’s long-running feud.
Talk about drama that could write its own album.
Taylor’s Take on It All
Years later, Swift opened up about the pseudonym in a candid chat with Paul McCartney for Rolling Stone. She called writing under a fake name “fun,” and explained that it helped her focus purely on the art — without the pressure of her brand. “You don’t want the work to become overshadowed by this thing that’s been built around you,” she said.
Even better? She later performed the song live during her Eras Tour stop in Liverpool, turning a once-secret track into a bold celebration of her songwriting legacy.
Hitmaker With or Without Credit
Whether her name is on the track or not, Taylor Swift proves time and time again that she can write a hit that dominates the charts and shakes the internet. From Speak Now to This Is What You Came For, Swift’s pen game is unmatched — even if she sometimes hides behind a Swedish-sounding name.
So next time you hear Rihanna belting out “This Is What You Came For”, just remember: Taylor was right there, pulling the lyrical strings behind the scenes.
