A song receives a certified all-kill (CAK) when it is No. 1 on the daily and realtime charts of Melon, Genie, Bugs, and Soribada along with the realtime charts of Flo and iChart. A perfect all-kill (PAK) is achieved when the song also becomes No. 1 on iChart’s weekly chart in addition to the criteria of a certified all-kill.

Rule Changes & Notes About Charts:

#1
Instiz iChart launched in March 2010. Although PAKs did happen prior to 2011, many aren’t counted because the charts are hard to find. Before 2015 there were 10 charts.

#2
As of 27 February 2017 — MelOn, Mnet, & Genie shift aggregation of real-time charts to between 12noon and 6pm only. Anything released not during that 6 hours will not count towards the chart until 1pm the following day.

#3
Early 2019 — FLO & VIBE streaming services've added to chart. FLO is owned by SM, JYP, & Big Hit. VIBE Music is a partnership of YG & Naver. VIBE is reported to replace Naver on the chart once launched.
