This list excludes cable show wins, since some shows do not award #1s to those who do not show up, like BTS or IU who are beyond that stage.
It also excludes those who have had no wins since the KPop era began in earnest on Sep 2007 with Big Bang's Lies.
JYP qualifies because his The House you Live one in Dec 2007, after the KPop era began.
Turbo qualifies because its Live, for the 20th year anniversary, won in 2016.
Cho Yongpil qualifies because his Bounce won in 2013.
