A new breakup track by Calvin Harris dropped Friday – but was it inspired by ex Taylor Swift?

Penned and produced by Harris, John Newman and the deejay-producer’s summery new reggae track, “Olé,” stirred reports that it was about Swift’s new romance with actor Tom Hiddleston.

Speculation arose that the lyrics seem to be from Hiddleston’s point of view, including a play on his Marvel character, Loki (“Low-key, you won’t tell none of your friends about me / You won’t tell them I occupy your dreams and your thoughts”) and a nod to Swift and Harris’ March tropical vacation. (“I see online that you’ve begun to be a good girl and take trips with your boyfriend, being attentive / Continue to pretend”).

However, a source tells PEOPLE that Harris – who split from Swift two weeks before her new romance went public – wrote it months ago. (At the time of the Harris and Swift split, multiple sources told PEOPLE there was no cheating involved with either party.)

Newman announced in a Wednesday Facebook live video that his longtime pal Harris had produced and written the “sentimental” track and that they’d filmed the music video in Mexico.

“This new track, ‘Olé,’ he played me, and I was like, ‘I’m not getting this; it’s not very much like me,’ and he said, ‘Well, it’s time to do something different; it’s time to do something a bit chilled,'” Newman said. “He’s a true, true genius and a very good friend … I’ve never actually released a song that I haven’t written, and Calvin wrote all this; it’s 100-percent publishing to him.”

Meanwhile, Swift and Hiddleston’s relationship has taken them across the globe since going public three weeks ago. So far, the couple have sojourned in Rome; his native U.K., where she met his mother; Rhode Island for her annual star-studded July 4th party; Nashville, where he met her parents; and, as of Thursday, Australia, where Hiddleston arrived to film Thor: Ragnarok.
