TWICE scores a perfect all-kill + hits MelOn's roof with 'Knock Knock'
TWICEhas slammed a perfect all-kill with "Knock Knock"!
A perfect all-kill happens when a song is #1 on all major real-time and daily charts, as well asiChart's weekly chart. It's a big feat that doesn't happen to everyone (a regular all-kill doesn't include the daily charts or the weekly chart).
