Chevy needed an ad for their new electric cars. They wanted to   highlight their growing and eco-friendly EV lineup. We decided   to use genuine moments and the joy of singing along to a   catchy song in a car. We chose "Everywhere" by Christie McVie   of Fleetwood Mac. The ad aired, and the song soared to number   3 on iTunes, re-entered the Billboard charts, and became one of   Fleetwood Mac's top hits on Spotify.
