Known as today’s digital-selling monsters in Korea, fourpiece SISTAR has become one of the most consistent groups in K-pop, with hit single after hit single elevating them towards the top of the K-pop girl group rankings. Since the K-Pop Hot 100 introduction in late 2011, SISTAR has the most No. 1s of any group (four), while two members have multiple solo No. 1s (leader Hyorin has three, singer Soyou has two). Meanwhile, the group’s splinter duo project Sistar19 — made up of Hyorin and rapper Bora — went on to be the biggest hit of 2013. Soyou also tied the all-time chart record when her solo hit “Some” spent six weeks at No. 1 atop the chart. SISTAR is a textbook example of how valuable a girl group can be when each member has charms and skills to ultimately make the entire outfit a supergroup.
