After sharing the song's demo with six different producers, Tegan finally decided to go with Greg Kurstin, which is how they ended up working with the Californian helmsman on Hearthrob
. She recalled to Under The Radar
: "When Greg Kurstin heard the demo, which was just a piano part off the top, an acoustic guitar, and some synths, basically, very stripped-down, he was the only producer out of all of the producers we talked to who was like, 'This is a pop song, a huge pop single ballad.' I was like, 'What?' It's awesome that he heard that.
When I wrote the song, I wanted to write something like Rihanna's 'Umbrella
.' Something really sad and kind of fu--ed, but something that everybody would relate to. So that's how we decided to work with Greg, because I felt like he really got me and got what I was trying to go for."
