"Gangnam Style" is a K-pop single
by the South Korean musician PSY
(short for psycho). The song was released in July 2012 as the lead single of his sixth studio album PSY 6 (Six Rules), Part 1, and debuted at number one on South Korea's Gaon Chart. On December 21, 2012 it reached over a billion views. Today it has about 1.25 billion views.
It actually is about the "class" that is to be found in the wealthy Seoul neighborhood of Gangnam
, whose residents are known to party a lot.
Although, most non-South Korean PSY fans take this to mean a silly horse dance.
