Brother and sister musician group Akdong Musician (Lee Soo-hyun and Lee Chan-hyuk) has maintained their #1 position on all the main online music charts for two weeks straight.

Taking a look at the online music chart from April 14 to 20 on the Melon music website (one of the best in the nation), the duo has fiercely kept off all competitors by placing on top with its debut album PLAY and its first title track "200%". In addition, Akdong Musician has kept a hold on its #1 position on other national charts such as Mnet's Genie, Ole Music, and Naver Music. With a total of 4 major online music chart wins under their belt, the duo is proving to be one of this year's most influential debuts.

Earlier this month, however, Akdong Musician has placed 2^nd on popular charts such as Bugs, Soribada and Daum Music. Their popularity has been steady and consistent.

"200%" is a love song that houses an upbeat, fun rhythm. They lyrics express the love of a girl, who prepares her confession overnight but fails to do so in front of the person she loves because of her extreme nervousness.
