A duet version featuring country singer Kane Brown was released in late April 2018, adding a new "layer of intrigue" to the track.
Many reviewers highlighted Cabello's ability to transition from a soft, breathy falsetto in the verses to a booming, belt-heavy chorus. Rolling Stone even ranked it as the 4th best song of 2018, calling it a "gigantic electro ballad" that proved she could handle any genre.
The track features a heavy drum hook that pays homage to The Ronettes' 1963 classic "Be My Baby," a detail frequently noted for adding depth to the song's "dark pop" sound.
The lyrics describe a "pain-is-pleasure" addiction to love, famously comparing a partner to nicotine, heroin, and morphine. While many fans found this "sultry" and "addictive," some critics, like those at USA Today, felt the lyrics were "frequently indecipherable" or "overproduced". Community Perspectives
