First comes love, then comes…a new song! As their new romance blooms, Taylor Swift and Calvin Harris have decided to take their relationship even further by mixing business with pleasure and creating an EDM collaboration track!

Ever since Taylor Swift, 25, and Calvin Harris, 31, were spotted holding hands during a recent trip to Nashville, the two musicians have put their relationship on the fast track – by deciding to work together! A source that Calvin has become so enchanted with Taylor, he desperately wants to take her career to the next level by featuring her on one of his upcoming EDM songs.

Taylor loves the idea of trying out an EDM sound. She’s very excited about getting in the studio with Calvin – and very flattered at how persistent he’s been when it comes to recording with her.

“Calvin is going after Taylor pretty hard, he’s been sending her songs and brought her out to Vegas, he wants to work with her and she’s said yes,” an insider tells. “She never saw herself as an EDM kind of girl but she’s  really changing as an artist, she doesn’t want to get put in one little box so she’s trying everything. She just wants to create great music, whatever form that takes.”

While Taylor is jumping at the chance to work with Calvin, she’s trying to take their non-working relationship as slow as she can.

“She likes [Calvin] but she’s not just going to jump into anything with him. She’s making guys work for it because she wants to make sure that it’s the right thing for her. At this point he’s still chasing her,” the source adds.
