Just two days into its release, 2NE1's comeback track, "I'm the Best", has been certified a 'perfect all-kill' by Instiz! The song swept the charts moments after its release, topping MelOn, dosirak, Bugs, Mnet, Cyworld, Soribada, and Monkey3 live. YG Entertainment's blog, 'YG-Life', took notice of the achievement and shared a screen capture of Instiz's certification. It shouldn't come as a surprise though, especially considering the streak of success the girls have been showing all year with "Don't Cry" and "Lonely". Congratulations! Source + Photos: Star News
