Happy was written and performed by Pharrell Williams for the Despicable Me 2 soundtrack in 2013 and later appeared on his 2014 album G I R L. The song became a worldwide number one hit known for its handclaps, soul-pop groove and simple chorus about feeling happy. Short excerpts circulated widely on video platforms as reaction audio, and this very brief cut keeps only the upbeat essence. Creators still reach for it because the association is instant, even for viewers who have not heard the full track in years.
