Acts may have felt sales spurts from TV placements, high-profile award wins and, of course, general fanfare.
When you consider we're in 2013, a look through America's 10 best-selling K-pop songs has expected and majorly-unexpected inclusions.
Unsurprisingly, PSY leads the count for top-selling K-pop track. But it's not with his 2013 single "Gentleman," a top-5 hit on the Hot 100; rather, t's with with last year's international smash "Gangnam Style," which is still selling the Korean rapper loads of singles. The 2012 single also landed at No. 55 on Billboard's year-end Hot 100 chart. Last year, "Gangnam Style" was at No. 47 on 2012's year-end chart.
PSY's slinky follow-up single "Gentleman" is the second-largest-selling K-pop track of 2013. Meanwhile, PSY's 2010 single "Right Now" -- which also boasts a high-energy electronic production similar to "Gangnam Style" -- is the eighth biggest-selling K-pop track.
