"Good For You" is the lead single from American singer Selena Gomez's second studio album, Revival (2015). 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 it was reworked by Lambroza, 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.
