Pharrell Williams speaks on stage during the United Nations International Day of Happiness 2015 at United Nations General Assembly Hall on March 20, 2015 in New York City.

Friday was the United Nation’s International Day of Happiness, and who better to ring in the day than Pharrell? Speaking to a crowd of students, the artist-producer told them that fighting for the environment was crucial to everyone’s happiness. “If you don’t have a home, then you don’t have a life. So we have to transition from ‘climate change’ to ‘climate action.’”

In concert for the big day, the U.N. also released the “world’s happiest playlist” as determined by Secretary General Ban Ki Moon and a bunch of celebrities from Ed Sheeran to Britney Spears. Strangely, Pharrell’s “Happy” is not on the list! Maybe that would have seemed like favoritism? (Pharrell, for his part, picked the Talking Heads’ “This Must Be the Place.”) Here’s a list of each celebrity and their picks from the UK Independent. You can listen to the playlist on MixRadio.
