The Fake Name Behind a Taylor Swift Smash Hit

In 2016, Calvin Harris and Rihanna dropped "This Is What You Came For," a song that shot straight to the top of charts worldwide. Fans loved the sleek pop production and the surprising songwriting credit that came with it.

That credit belonged to someone named Nils Sjöberg, listed as a Swedish songwriter nobody had ever heard of before. No interviews, no social media, no past discography. Just a name attached to a massive hit.

Music blogs and curious fans tried digging up information on this mysterious Sjöberg, but nothing turned up. It seemed strange that a total unknown could co-write one of the biggest pop songs of the year.

The mystery didn't last. Within months, it was revealed that Nils Sjöberg was a pseudonym for Taylor Swift, who wrote the track while she and Calvin Harris were dating and kept her involvement private.

Swift later confirmed the truth herself, explaining she wanted to write the song purely as a creative gift without her name influencing how people received it. At the time, she was also trying to keep her songwriting separate from her pop star image following her relationship with Harris.

The fake name wasn't just a whim. Swift had reportedly used the alias before, and industry insiders say the choice let the song stand on its own instead of becoming instant tabloid fodder.

Once her name was attached publicly, the story became almost as big as the song itself. It turned a chart hit into a lesson on how even massive stars can hide in plain sight, credited under a name nobody thought to question.
