Psy - Gangnam Style

Anyone who's been following South Korea's K-Pop scene would have known that it was only a matter of time before it spawned an international hit, but few would have predicted it would have created a monster on the scale of Psy's 'Gangnam Style'. Back in August, the song's outlandish video - which featured the smartly-dressed, sunglasses-wearing Psy performing a bizarre 'invisible horse' dance in a variety of unusual locations - caused a huge splash when it was posted on YouTube, and subsequently surpassed a billion views within 4 months, beating Justin Bieber's 'Baby' to become the most-watched YouTube video of all time.
