"Ganji" was offered to Jessi while she was performing her latest single, "Zoom". Psy attempted new flow styles in the song and reflected the frustrations of translating Jessi's English lyrics into Korean. Psy asked Sung Si Kyung to feature in the song "You Move Me". Despite being a frequent collaborator with Sung, he found it was more awkward to request him to participate in the song. The song is about life, and Psy felt the song was finished with Sung's special diction regarding the song's Korean lyrics. "Sleepless" was recorded in a single day; Psy has stated that he hoped it would heal people's souls who are tired from a hard night at work. "Happier" was finished in 2019 before Crush became part of Psy's company P nation. "Celeb" was originally going to be released in 2019, but was delayed due to Psy's attempt to pair the emotionality of a song like "Celeb" with a typical party song like "Champion" to balance the album, a strategy he tried to keep throughout his previous albums. Psy wrote "Forever" at dawn when he feared that he would miss the fullness of his performances and that feeling might not come.
