Pharrell's Oscar-nominated hit song "Happy" has become an anthem to people around the world. As soon as the beat drops, it's hard to avoid busting a move.
People around the world, from Hong Kong to Jamaica, have created their own versions of the song, and they all have the same message of self-expression and spreading happiness.
Pharrell partnered with the United Nations today to honor the International Day of Happiness, so this song is today's official theme song.
