Gangnam Style

Gangnam Style has broken yet another international record. The K-pop hit by South Korean star Psy has become the most watched video on YouTube of all time with over 816 million views. It's taken the crown from Justin Bieber's first single, Baby, which has amassed nearly 805 million views. The hit contains little English, and is apparently a parody of the lavish lifestyles enjoyed in Seoul's upper-class Gangnam district.
