As you well know, Rain and Jackie Chan are good friends, remember the concert a few years ago (can't remember when) in China where Jackie Chan and Rain both performed then they got to know each other blah blah blah....

well, thy had a recent get together and Rain's Hip Song has been chosen as the korean OST for "The karate kid" which is an upcoming hollywood movie where Jackie Chan is starring.

Although you might think the song and the movie doesn't go well (i know) it's just a promotional mv for the movie so everything's cool
