Watch a huge pop video from the 21st century and there's a good chance you'll spot Pharrell Williams. He has been a highly visible part of the new millennium's music videos, whether he's performing as a solo artist, like on the megasmash "Happy" and the hyperactive "Come Get It Bae," or adding his winking ad-libs and next-level production techniques to hip-hop and pop icons like JAY-Z and Calvin Harris.
