블랙핑크는 세계적으로 사랑을 받던 ‘2NE1’ 이후 YG엔터테인먼트에서 7년 만에 새로 선보인 걸그룹으로, 그야말로 엄청난 기대와 부담을 짊어지고 데뷔했다. 데뷔 팀과 데뷔 시기가 엎어졌다가 뒤집히기를 반복하면서 ‘과연 얼마나 대단한지 보자’는 듯한 대중의 시선이 한껏 모이던 2016년 8월 8일, 블랙핑크는 ‘휘파람’이라는 곡과 함께 등장했다. 발매 직후 휘파람은 모든 음악 차트의 1위를 독식했고, 꾸준히 성적을 유지하며 ‘2010년대 최고의 K-pop 100곡’에서 26위를 차지하는 기염을 토했다. 가요계에 문이 있다면 가히 그 문을 부수고 들어왔다고 볼 수 있는 파괴적인 등장이었다.

그런 그들이 어느새 5년차 가수가 됐다. 하지만 안정기에 들기는커녕 여전히 말도 안 되게 가파른 상승세를 보이고 있다. 행보마다 새 기록을 세우는 신기록의 아이콘 블랙핑크의 매력은 어디까지일까? 지수법칙을 통해 알아보자.
