“BOSS” is a song comprised of the seven members, including TAEYONG, JAEHYUN, WINWIN, MARK, DOYOUNG, JUNGWOO, and LUCAS. It’s an urban hip-hop song composed of heavy bass riffs as well as rap and vocals from the members.

The lyrics tell the listeners that the modern society needs true empathy rather than fragmentary and superficial communication, which ultimately hold the aspirations that NCT will arouse that empathy. In addition, TAEYONG and MARK have participated in writing the lyrics for the rap.
