YouTube star Psy's 'Gangnam Style' song debuts on multiple lists.

South Korean artist Psy is dancing his way up Billboard's charts with his viral phenomenon single, "Gangnam Style." This week, Psy leaps 9-1 on the Social 50 while the tune hops onto Heatseekers Songs at No. 23 and bows at No. 74 on Hot Digital Songs with 23,000 sold (up 96%), according to Nielsen SoundScan. (That's the largest sales week for a title on World Digital Songs, where it remains at No. 1.) The infectious track has been gaining in weekly sales due to the popularity of its video, which has earned more than 75 million views on YouTube. So far, "Gangnam Style" has sold 57,000 downloads in the United States following its release on July 15.

While U.S. radio isn't quite embracing the song, it is making inroads. Notably, top 40 KAMP in Los Angeles, the second-largest radio market, added the song last week, playing it 24 times. Those detections amounted to 66% of its overall Hot 100 Airplay audience for the week ending Aug. 26. Rhythmic KDDB Honolulu accounted for the second-most audience, with 57 plays.
