Rapper Psy's "Gangnam Style" ranked number 1 on the U.S. iTunes Weekly Single Chart.

On Monday, Psy was able to beat Bruno Mars for first place.

In third place was Rihanna and fourth with Ke$ha.

This chart is based on the number of downloads and so Psy won the past two weeks with first place.

He did slip down to number 2 during the first week of October, but he is back at number 1.

Psy recently won the 'Best Video' award at the MTV EMA's and plans to attend the AMA's as well.
