In the Atlantic. Here is the absurdly wonderful original video (if you weren't one of the 56M+ people who already watched it):
Gangnam is a tony Seoul neighborhood, and Park's "Gangnam Style" video lampoons its self-importance and ostentatious wealth, with Psy playing a clownish caricature of a Gangnam man. That alone makes it practically operatic compared to most K-Pop. But I spoke with two regular observers of Korean culture to find out what I was missing, and it turns out that the video is rich with subtle references that, along with the song itself, suggest a subtext with a surprisingly subversive message about class and wealth in contemporary South Korean society. That message would be awfully mild by American standards -- this is no "Born in the U.S.A." -- but South Korea is a very different place, and it's a big deal that even this gentle social satire is breaking records on Korean pop charts long dominated by cotton candy.
