Solo was released in November 2018 as the debut solo single by South Korean singer Jennie, a member of BLACKPINK, while the group was rising to global popularity. The track mixes pop, dance and hip hop elements and centers on independence after a breakup, a theme reflected in its widely shared music video and choreography. Short excerpts continue to circulate on fan edits and social platforms, where the recognisable hook is used to signal confidence and a standout solo moment.
