BTS Cypher PT.1 is the foundational entry in the group's iconic rap series, released on September 11, 2013, as the seventh track on their first mini-album, O!RUL8,2?. It features the "Rap Line"—RM, SUGA, and j-hope—delivering aggressive, raw verses over a beat produced by Supreme Boi . Unlike the later, more polished installments, Part 1 serves as a gritty declaration of their hip-hop identity during their rookie era.
