Psy's "Gangnam Style" has taken a step down to number 2.

On October 7, the official chart company announced that for the second week of October, Psy's "Gangnam Style" has been pushed down to number 2 by Rihanna's "Diamonds."

However, the official chart company also stated that the difference between the two was not that big.

Number 3 was One Direction and number 4 is Adele.

Psy has recently become a global sensation with his song, "Gangnam Style." He has ranked number 1 on iTunes in 30 countries and has ranked number 2 on the U.S. Billboard Main Single Chart 'HOT 100'.

He has appeared on many shows such as the "Ellen Show" and "SNL" and featured on news programs such as NBC and CNN.

He has also recently signed a contract with Justin Bieber's agency and plans to release his first U.S. single sometime in November.
