Psy's historic "Gangnam Style" is continuing to make history.
The MV, which was the first YouTube MV to hit 1 billion, is continuing to make steps as the most-watched K-pop MV. It has just hit 4 billion views, much higher than the 1.5 billion that BLACKPINK's "DDU-DU DDU-DU" has as the second-most watched K-pop MV.
Congratulations to Psy! You can watch it again above.
