Songfacts®:

• This is the second single and title track from Canadian singer/songwriter Carly Rae Jepsen's debut EP. Like much of the record, it was penned with her long-time collaborator, writer/producer Ryan Stewart, who is also the frontman of the Canadian pop-punk band Marianas Trench. It was released on February 24, 2012.
• The song finds Carly singing about a bad boy who treats her badly, but she can't get out of her mind. It came out differently to anything she'd done previously - more poppy than her other folk-styled tunes. "I was singing it in the mic, to demo it out, with these guts that I didn't know I had," Carly recalled. "And it was exciting. It was like a braver version of me that I never had experimented with before, at least not out loud to people."
  
  Carly didn't know what to do about the new song, wondering how it would fit on the record. For eight months, she and Stewart wrestled with it, before concluding that pop had just as much a place on the EP as folk.
• This was produced by Dallas Austin, an Atlanta-based producer behind several '90s hits, including TLC's "Creep" and "Unpretty" and Brandy & Monica's "The Boy Is Mine."
