Pharrell Williams wants to make your day — all 24 hours of it — a little more Happy. The songwriter, rapper and producer released a 24-hour music video for the smile-inducing song Happy (the 4-minute track plays on loop 360 times in a row). The interactive video allows you to pick any time of day and you'll see either Pharrell or equally stylish lip-syncing dancers being infectiously, well, happy. See the official music video below.
