"Call Me When You Break Up" is adance-pop[2] andpop rock[3] song, opens with avoicemail tone, but not in the traditional sense ofR&B stars singing over lovelorn recordings from their answering machine. Gomez and Abrams are the ones leaving a message at the beep. “Call me when you break up/Unless you’ve found the person that you want a new name from/I’d to be there when the day comes/You know I’m always here, so don’t ever be a stranger,” Gomez sings. Blanco toldInterview, that the song was recorded at home, and the couple did not go to the studio every day, but preferred to record the album at home: "I’d be like, ‘Hey, I have this cool chord thing.’ Then she’d come in. We weren’t like, ‘Today’s the studio. We’re going to write this song and that.’ So many times it was so hodgepodge. It was like two hours here, two hours there. I’d never worked that way with someone. Usually I work that way if I’m by myself, but it was so cool to be able to do that with her".[11]
Jason Lipshutz fromBillboard praised the song, describing it: "such fizzy joy that its two-minute run time flies", writing that Gomez and Abrams need to keep recording together and "letting their personalities ricochet off each other".[12]The Stardust magazine, wrote that: "Gomez and Abrams' voices blend seamlessly, with Abrams' charismatic, introspective style complementing Gomez's soft, emotive delivery", adding that Blanco's co-writing "added to the creative synergy behind this string-enhanced pop collaboration".[13]
