Do you know why you love Gangam Style? Probably because everyone around you loves Gangam Style. Even though 9 in 10 of us don't get the joke (Gangam Style is a spoof on Koreans living-above-their-means) we still love it - and love to hate it when it's overplayed.
For most of us, Gangam Style is the Macarena - fun just because everyone else is enjoying it.
We enjoy herd mentality. We enjoy being part of something, dancing together, living together, laughing and celebrating together. Music binds us. Even when we don't get it.
