Danielle Haim explained the song's background to Pitchfork
"We were obsessed with this idea that, throughout every decade, there'd be songs that we love that hearken back to that '50s rock vibe: the one-four-five, piano eighth notes—the [miming playing a keyboard] dink-dink-dink-dink-dink-dink-dink-dink! Whether it was Tom Petty in the late '70s or the Clash in the early '80s, or even like, OutKast's 'Hey Ya
' - they all hearkened back to this '50s doo-wop thing. So we wondered: What does it sound like in 2017?"
