What was the name of the kpop song on the 2011 AP Music Theory exam?

It began with an introduction on like, a saxophone or something. Then there was a brief pentatonic, stereotypically Asian instrumental part, followed by this insanely complicated drum solo. A male soloist sung a verse, and his voice was mimicked by this traditional flute thing, then the crazy drum solo repeated, and he sang another verse. Then the excerpt was over. By the way, it isn't that ANAYA song that everyone keeps mentioning.
