"BDZ", an electropop song, was composed by J. Y. Park, with the Japanese lyrics penned by Shoko Fujibayashi and Yu Shimoji. It is about "moving forward and pushing away obstacles like a bulldozer" and "conveys feelings of strength and starting anew." Park stated that it is "a song for fans and Twice to sing and enjoy together."[1][8][9]
The Korean version of "BDZ" was released on November 5, 2018, as the seventh track of Twice's sixth extended play (EP) Yes or Yes. The group performed the song during their comeback showcase for the EP, as well as on South Korean music programs.[10][11]
