As the world is set to mark the third International Day of Happiness on Friday, the United Nations has called on netizens to share the songs that makes them happy, as part of its #HappySoundsLike campaign. 

The UN, which said it is "using the power of music to inspire hope," also released the "happiest playlist," taking contributions from music stars such as David Guetta, James Blunt and Ed Sheeran. 

"On this day we are using the universal language of music to show solidarity with the millions of people around the world suffering from poverty, human rights abuses, humanitarian crises and the effects of environmental degradation and climate change," said UN Secretary General Ban Ki-moon. 

Twitterati have been sharing their "happiest" songs under the hashtag #happysoundslike, and five of these songs will make it to the UN playlist.
