The steamroller that is IU seems to never stop! After an all-kill performance with her follow-up track 'Friday', she has nabbed the coveted 'perfect all-kill' on the South Korean music charts.

A perfect all-kill ("PAK") happens when an individual song sweeps all of South Korea's major music charts and places first on the weekly iChart on Instiz.

This is IU's second perfect all-kill of the year, following her success with 'The Red Shoes' in October!

This victory is all the sweeter considering that IU personally wrote the song herself! Take the music video for another spin below.
