The 'PSY and Bieber Face Off' infographic compares the two mega pop princes on their number one YouTube hits. Previously the record holder, Justin Bieber topped the charts with his single 'Baby.' The newcomer, PSY, has recently stolen the spot and reached well over a billion views with Gangham Style.

However, the ultimate deciding factor may be the staying power of these two pop stars. Bieber has released multiple albums to great success whilst PSY has really only had his one major hit. However, this major hit has racked him up quite the celebrity fan club including Britney Spears, Ellen Degeneres, Heidi Klum and the United Nation's Ban Ki-Moon.

If social media is any determinant of popularity, PSY has a while to go before he overtakes the Justin Bieber fanclub.
