+1 for "Gangnam Style is a poignant example of a world-wide entertainment trend that wasn't started in America". You said it.
I wanted to say that too, but didn't feel it was necessary within the discussion context taking place (where I was first replying). Since you've mentioned it, here's my view. There's a certain "uninhibitedness" to the video that's very recognisably asiatic (as in there is no 'Made in USA' cultural feel and reference to it) and that also that shouts out "I am not a packaged deal, I was spontaneously made". I think that freshness is what's keeping the momentum going.
