Released on Friday, Nov. 21, "Good Boy" starts atop the chart with just three days of sales, moving 5,000 copies according to Nielsen SoundScan.
It's a big accomplishment for the duo's Korean record label, YG Entertainment, who boast the only K-pop acts to top Billboard's World Digital Songs chart: PSY(who previously topped the chart with "Gangnam Style," "Gentleman" and "Hangover") and 2NE1 (who ruled this year with "I Am the Best") are also under the agency that also houses BIGBANG, Epik High, Akdong Musician and more.
