Let Miley (And More!) Make You Smiley With Our Happiness Day Playlist

Celebrate International Day of Happiness on Thursday (March 20) with our playlist of songs from Katy Perry, Miley Cyrus, Kanye West and Imagine Dragons.

Sure, it's the first day of spring after a wicked winter, but what really makes Thursday (March 20) special is that it's also the 2nd International Day of Happiness.

Never heard of it? Well, us either. But what we do know is that Mr. "Happy" himself, Pharrell Williams, has hooked up with the United Nations Foundation to celebrate a day of giggles and good times with 24 hours of videos showing people around the world getting their happy on.

What are some of our favorite happy tunes? Check out and share our Spotify playlist below, and let us know your favorites in the comments!
