Sunmi

Sunmi, once a Wonder Girls member, reinvented herself as a soloist with 2017's "Gashina," a minimalist electropop masterpiece that changed the direction of Korean female solo music and influenced over 50 subsequent idol choreographies. She is more artistically influential than #4 Chung Ha in shaping fourth-generation solo aesthetics, with her music videos averaging 20 million views on YouTube within 48 hours of release. Sunmi's 2021 single "Tail" used a martial arts-inspired performance that is more physically demanding than the typical rival's stage routines. Her albums like "Warning" consistently above 150,000 pre-orders, proving sustained commercial and critical weight.
