[14] The New York Times's Jon Pareles wrote, "The sacred-secular juxtapositions continue in the title song, a Pharrell Williams production that switches between gospelly piano chords — as Ms. Grande praises how her man can 'bring the bitter taste to a halt' — and more dissonant hip-hop as she enjoys how 'you make me say 'oh!''.
[16] The Guardian's Alexis Petridis said, "the title track offers a bizarre, gripping splice of earthy Carole King-ish singer-songwriter piano ballad with Migos-inspired hip-hop, complete with onomatopoeic vocal interjections".
Brittany Spanos of Rolling Stone called the song a "bouncy, almost wickedly catchy highlight" on the album.
Arriving midway through the album, 'Sweetener' sees Grande sing effervescently about 'letting the sweetener in our hearts' to 'bring that bitterness to a halt', before she ushers in a trap breakdown thats sounds like Metro Boomin messing with The Little Mermaid soundtrack.
"[20] Chris DeVille of Stereogum said, "The title track is the sort of modernized throwback soul tune Meghan Trainor might release, but rendered tastefully and produced with the detail-rich minimalism of Spoon's Kill the Moonlight.
"[12] Pitchfork ranked it on its 100 best songs of 2018 list, saying that "amid the track’s svelte production — trickling percussion, cushy bass hits, a lusty and cascading synth line — Pharrell punctuates Grande’s commands with a high-pitched “sheesh!” like a steam whistle cutting through the air.
“Sweetener” carries a tender streak, too, embracing the notion of finding the good in so much bad, and toasting to the people in one’s life who encourage such perseverance.
