Pharrell Williams — Happy - From "Despicable Me 2"

Pharrell Williams' most durable single is broadly present across the global charts again, appearing on 102 country and platform charts after a three-week dip. Written and produced for the Despicable Me 2 soundtrack before becoming the lead single from his album G I R L, the track reached number one in 35 countries and stood as the best-selling song of 2014, per Last.fm. Its architecture is deceptively simple — a falsetto hook, a hand-clap pulse, no bridge to speak of — which is precisely why it has survived a decade of playlists, weddings, and children's-movie rewatches. The song's afterlife has been steady rather than spiky. Its return to this width of chart presence is worth clocking.
