PSY is still taking over the charts with his hit song ‘Gangnam Style’, and he again makes history with the first ever K-Pop song to reach number one on Billboard’s Digital Songs chart. He even beat out popular artists such as Taylor Swift, Owl City, Maroon 5, and Flo Rida. Although PSY is now quite popular around the world, he is still currently number 2 on the ‘Hot 100′ chart, below Maroon 5. A week ago, PSY pledged to dance shirtless if ‘Gangnam Style’ reaches number one on the ‘Hot 100′ chart. I guess we just have to wait before he takes his shirt off.
