[3] A teaser for the lead single's music video was released the following day, featuring the members handing out denim jeans to students in a classroom, with a cameo appearance from singer and actress Uhm Jung-hwa.
[6] The song's title in Korean, "청바지" (cheongbaji), refers to a common drinking cheer in South Korea.
[7] Throughout the song, the lyrics explore the concept of youth being a mindset rather than age, encouraging the listener to put on jeans and enjoy the moment.
[8] In her review of the album Teleparty, NME's Carmen Chin commended "CBZ (Prime Time)" for its musical experimentation, highlighting its "refreshing callbacks to the more understated retro eras of pop music", which is best embodied by the song's incorporation of swing jazz and country.
Intended as a celebration of youth, it depicts individuals from various walks of life, including exhausted students and office workers, a distressed mother, and a teenage daughter, joining BSS in a joyful chant of "CBZ" to convey the message of the youth being anyone who finds joy in the moment.
