I would like to differ. People dancing, pretty girls as eye candy is a universal trend that definitely didn't start out of the MTV generation. See for e.g. Bollywood movies.

Actually, my understanding is that the lyrics are a parody of the Gangnam district of Seoul, and how the rich people there try to act as if they're American, not Korean.

If anything, it's a parody/rejection of Western culture.

I think the appropriate word you're looking for (or rather, to be used instead) is "satire". And that completely changes how you view the whole thing.
