Lil Dicky has a new song out, but Earth is no ordinary pop song. It was written and recorded to commemorate Earth Day.

As you may have guessed from the name, Earth is all about this planet we call home. And, more importantly, why we need to start doing more to save it.

Earth has gone viral, partly because of the subject matter, but also because of the number of celebrity cameos involved.

Each animal or plant you see in the music video for Earth has been voiced by a different celebrity. Including Justin Bieber, Snoop Dogg, and Ed Sheeran.
