Sabrina Carpenter and Pop’s Next Gen Have a Secret Weapon: Amy Allen

Some well-played profanity can make a pop song sizzle.

But few expletives in recent memory have had the potentially career-altering crackle of the one let fly by Sabrina Carpenter, a former Disney Channel star, on “Please Please Please,” her Dolly Parton-meets-Abba confection that became a surprise No. 1 hit this summer.

“Heartbreak is one thing, my ego’s another,” Carpenter flutters, before a plea to a new fling: “I beg you, don’t embarrass me, little sucker” — except instead of little sucker (the radio edit), she rhymes an unprintable four-syllable term of tongue-in-cheek endearment, dropping her voice low and lathering it in a knowing hillbilly sass.

Carpenter sells it. But she had help — a playful, foul-mouthed voice in her ear insisting that a pop star these days might as well run Dolly through a TikTok-friendly system update, or sneak a Dada phrase like “that’s that me espresso” into the cultural lexicon.

“Five years ago, I would have never thought it was OK,” said Amy Allen, the hit songwriter credited on “Please Please Please,” along with “Espresso” and every other track on Carpenter’s breakout album, “Short n’ Sweet.” But Top 40, in no small part thanks to Allen, is entering a much-needed era of quirk, in which regular jolts of the unexpected are cutting through a sludge of smooth-brained content.

“Now I feel scared of generic things that sound like No. 1s,” said Allen, 32, who landed her first chart-topping hit, “Without Me” by Halsey, five years ago. “Listeners are just getting smarter and smarter now,” she added. “They want something to be odd, something to be off, something to be really catchy and unexpected about a lyric or melody. The days of really polished pop are shifting out.”
