Pharrell Williams knew what he was about when he sang 'clap along if you know what happiness is to you' - for many, it means a song.
Do you have a song that can instantly uplift you, cheer you up, make you happy? Turn on the music, play and share the song that makes you smile. Today, March 20, marks the International Day of Happiness, and this year award-winning musical celebrities such as AR Rahman, James Blunt, Fatboy Slim, Ed Sheeran and John Legend are urging you to be a part of the United Nation's #HappySoundsLike Campaign.
The campaign's objective is to encourage people to share happy-making songs and spread goodwill and cheer to others in less cheerful circumstances. "We're using the power of music to inspire hope for a better tomorrow," the United Nations said in a tweet.
This global celebration is nothing short of a Friday party and eager twitterati are making the most of it. Here's a selection of happy songs picked by celebrities:
