Rapper Psy claimed the No. 1 spot on the iTunes Top Songs Chart on Saturday with his single "Gangnam Style," becoming the first Korean to achieve the feat.
YG Entertainment, Psy's agency in Seoul, said the singer's appearance on NBC's "Today" on Friday seems have helped boost the song's popularity. The iTunes chart accounts for about 80 percent of the U.S. online music market, making Psy's feat all the more laudable as U.S. fans remain hooked to his addictive "horse-riding dance" and punchy melody.
Earlier, Psy performed his hit single live on ABC's "Good Morning America" and made a surprise appearance on NBC's "The Ellen Show," during which he taught the host and Britney Spears his signature dance moves.
"Gangnam Style" quickly became a global sensation after the music video was released on YouTube on July 15. The official version of the video had attracted over 175 million hits as of Saturday.
