Rain - Hip Song

This is the song that is being used in the international (ASIA) markets to promote the Karate Kid film, as it appears in the movie trailer. The whole performance is a dance routine, and there are other videos of him and his dancers doing the same moves for the song, but just looks better in a suit.

Rain is a K-Pop star and he pretty big all around the world, expect the USA. He is also featured in a couple of Time Magazine articles a few years back as well, on one of those 100 people list.
