What is your opinion of the song "Gangnam Style"?

Have you heard the song Gangnam Style ? I was briefly introduced to this song by my son and it was quickly filed as “stupid” by me, since I only understand 3 words in the whole damn song because it is sung in Korean. I am very into punk and heavy metal music, and this is about as far from it as you can go, but I’ll be damned if I don’t find this song extremely catchy now. What do ya think?
