On December 27, the website for music magazine Spin revealed their favorite pop singles of 2011. Among the various songs by A-list pop icons, two K-pop songs made it to the list. At #3, HyunA's "Bubble Pop" beat #4 pop princess Britney Spears' "Till the World Ends", and 2NE1's "I Am the Best" took the #8 spot. HyunA & 2NE1's appearance on this list is just another example of the Hallyu wave's continuous expansion across the world. Congrats to both of these artists! Source + Image: Spin magazine
