Good for You (feat. A$AP Rocky)

"Good For You" is the lead single from American singer Selena Gomez's second studio album, Revival. It features vocals by American rapper ASAP Rocky. The song was written by Gomez, Julia Michaels, Justin Tranter, ASAP Rocky, Hector Delgado, and its producers Nick Monson and Nolan Lambroza. Originally, the track was conceived by the writers in 45 minutes, during a session booked by the latter. The singer then received the song through the trio's A&R and was entirely involved in its creative session, helping to develop it as a representation of her process of self-realization, her confidence as a young woman, and her feelings of vulnerability. After Lambroza reworked it, she sent the song to Rocky, who added new instruments and co-produced it with his frequent collaborator Hector Delgado, who was in charge of Rocky's vocal production.

After anticipation by Gomez, "Good for You" was digitally released on June 22, 2015, by Interscope and Polydor Records, serving as Revival's lead single as well as the first song by the singer to be released through those labels. A torch song, it is a pop and electro-R&B slow jam with hip-hop elements that comprises a mellow, low-key snap-drop hip-hop beat reminiscent of modern, pitched-down Southern hip-hop productions, minor sound bursts, percussion instrumentation, drum machines, airy and transparent synthesizer, and a minimalistic bass. Gomez sings atypically with breathy vocals and a plaintive timbre in the track, which was noted for being her first collaboration with a rapper. Its come-hither lyrics have intensity, psychodrama, self-confidence, and female empowerment as main themes, dealing with pleasing her lover and being the perfect complement for him. Rocky raps his verse at the end of the song, which is written from a male, player's perspective and features braggadocio, profanity, and sexual innuendos.

"Good for You" received acclaim from music critics, who praised its minimalistic production, sex appeal, and Gomez's vocals, as well as her maturity and artistic growth; some of them, however, had mixed reactions towards Rocky's contribution. Reviewers also compared her vocals to those of Lana Del Rey, Imogen Heap, and Lorde, while noting similarities to the works of Del Rey; it was later included in many year-end lists of best songs. Commercially, the song reached the top twenty countries as Australia, Austria, Canada, Denmark, France, New Zealand, and Spain, as well as the Czech Republic and Slovakia's digital charts. In the United States, it debuted at number nine on the Billboard Hot 100 and later peaked at number five, becoming her highest-charting single until 2019 when "Lose You to Love Me" topped the chart, as well reached the Pop Songs Summit, where it became her first song to do so.

Its accompanying music video was directed by Sophie Muller and premiered on Times Square screens on June 26, 2015. The project uses a new and slower version of the song, which omits Rocky's verse and features string instrumentation. Highlighted for its provocative imagery, it follows a low-key premise with Gomez wallowing on several vignettes wearing several casual outfits. A second version was later released using the explicit edition of the track and features Rocky rapping his verse with Gomez's scenes and dynamic visuals in the background; new shots are also present in this version. Both videos received positive feedback from critics, who praised the singer's sensuality and the growth in her artistic imagery, describing the first as her "most intimate" to date and comparing it to Del Rey's works. To promote "Good for You", Gomez did interviews on the radio and a few live performances in shows such as Today and Taylor Swift's The 1989 World Tour (2015), where she made her first live performance and served as a special guest.
