Larsson released the single "Crush" as the latest preview of her then upcoming fifth studio album, Midnight Sun. Recorded at Just for the Record, the track was written with Helena Gao and produced by Margo XS alongside Larsson's longtime collaborator MNEK. "Crush" follows the album's title track, "Midnight Sun", which came with a Charlotte Rutherford-directed Y2K-inspired video.
Released as Larsson continued her North American run with Tate McRae, the single also preceded her upcoming European headline tour and further Australasian dates with OneRepublic.
Lyrically, "Crush" explores the conflict of developing feelings for someone new while already being in a stable relationship. In the percussive pop track, Larsson sings about experiencing a new infatuation that she describes as a "fantasy" interfering with her existing relationship. The lyrics reflect the tension between excitement and the recognition that it could disrupt what she already has, while also acknowledging the emotional impact of the situation. According to Contactmusic.com, the song starts with subdued instrumentation and a "shuffling" beat before developing into a more insistent rhythmic drive, while the lyrics address the singer's conflict between temptation and loyalty.
"Crush" peaked at number 32 in Sweden and number 56 in Norway, while also reaching number 34 on the New Zealand Hot Singles chart. In the United States, the song topped the Dance/Mix Show Airplay chart, reaching number 11 on the Hot Dance/Pop Songs and number 17 on the Pop Airplay.
