Pharrell Williams just released a music video, "Happy," that is airing for 24 hours straight and features several different people dancing and lipsyncing the catchy tune.

The simple song, which is featured on the "Despicable Me 2" soundtrack, features lyrics such as: "Because I’m happy/ Clap along if you feel like a room without a roof/ Because I’m happy/ Clap along if you feel like happiness is the truth."

Williams appears in the video along with several other regular folk swaying and singing the song. There are also cameos by "Despicable Me 2" star Steve Carrell, rapper Tyler the Creator, former NBA star Magic Johnson and actor Jamie Foxx.
