Taylor Swift has dumped her pseudonym and has now officially claimed credit for co-writing Calvin Harris’ ‘This Is What You Came For’.

The Rihanna featuring song had originally stated that Harris and Nils Sjoberg wrote the track.

Fans had long suspected that Taylor had helped Calvin make the song, but now their suspicions have been confirmed.

As reported by TMZ, Sjoberg has now been removed from the track on BMI – which protects licenses for songwriters – and has been replaced by Taylor Swift, whose name now sits alongside Calvin’s.

Why did Swift hide her name? Did she want the public’s focus to stay on the music and not her former relationship with the Scottish DJ? We can only speculate.

What we’d like to know is just how many songs Nils Sjoberg has featured on. How many other songs out there has Taylor secretly been writing? We might just get back to you on that…
