In an interview with Pitchfork, Robyn said that

Me and Rudolf [Nordström, aka Mr. Tophat] started working on the track in a house in Ibiza a few years ago. But it’s really Rudolph’s track: He’s the one who created that world. And I loved it. It was kind of like “Send to Robin Immediately”: I just heard something that I was really inspired by and I wrote a song on it. We worked with analog synths and the vocals and arranged it all together. I work that way a lot: Rudolf will make stuff, and I will edit it, we’ll take turns. He is so amazing at creating music that can put you in a trance.

Maybe that beat is inspired by my samba lessons. I always loved samba music—it makes me cry. I had to learn how to dance to samba because the music is so moving to me. My friend has been dancing for a long time—when I was low and wasn’t making music she would come by and give me lessons.
