• Every good pop album needs a front door and a back door. Sabrina Carpenter opens Man's Best Friend with the kick of "Manchild," a scolding little portrait of a partner who seems to have misplaced his emotional car keys, and she slams it shut with "Goodbye," a disco ball of a breakup song that twirls bitterness into catharsis.
• "Goodbye" is ABBA by way of Jack Antonoff: an orchestral disco swirl with strings that provide lush, dramatic backing and harmonies stacked like sequins. The subject matter, however, is a lot less glamorous. Carpenter had been dating actor Barry Keoghan for about a year, from December 2023 to December 2024, before the relationship abruptly imploded. People magazine reported that the two were "young and career-focused" and decided to take a break. Carpenter's song tells it rather differently.
• The lyrics accuse a partner of switching off their affection "overnight," of breaking her heart "on Saturday," then sticking around with the faux-friendly chumminess of someone who still wants to text. "Can't call it love, then call it quits. Can't shoot me down, then shoot the s–t," she snaps. That's not a Hallmark card sentiment; that's someone who's had their Sunday ruined.
• One curious detail: Carpenter sings "on Saturday," not "on a Saturday." The absence of that little article makes it sound like reportage - this happened last weekend, thank you very much - pinning the breakup to a calendar page. She's used this time-stamp trick before, most notably in "Skinny Dipping," where she carefully sets her scene on a Wednesday at a coffee shop.
• And then there's the multilingual flourish. Throughout "Goodbye," Carpenter says farewell in at least six languages: Japanese ("sayonara"), Spanish ("adiós"), Italian ("arrivederci"), French ("au revoir"), even British English ("cheerio"). At one point she slips in "por siempre te amo" ("forever I love you"), only to snap the door shut again. It's both playful and pointed: her ex may not be bilingual, but surely he can grasp that goodbye is goodbye in any tongue.
• If Man's Best Friend chronicles Carpenter's romance with Keoghan - as fans and critics widely believe - then the sequencing feels deliberate. "Manchild" opens the book with immaturity, tracks like "Tears" and "House Tour" capture the relationship in full swing, full of intimacy and messy devotion, and "We Almost Broke Up Again Last Night" reads like foreshadowing. Finally, "Goodbye" arrives not as an ellipsis but as a full stop.
• In the long pop tradition, the last track is often the curtain call, the moment the artist turns off the lights and leaves you humming in the dark. Carpenter doesn't just turn off the lights; she slams the switch down, says farewell in six different dialects, and leaves Barry Keoghan - and anyone else listening - in no doubt that the party is very much over.
