The Golden Record is basically a 90-minute interstellar mixtape — a message of goodwill from the people of Earth to any extraterrestrial passersby who might stumble upon one of the two Voyager spaceships at some point over the next couple billion years.

But since it was made 40 years ago, the sounds etched into those golden grooves have gone mostly unheard, by alien audiences or those closer to home.

If you've ever undertaken a creative endeavor, you may have found that inspiration doesn't always come when you're creating; sometimes, it strikes when you put your work down and walk away.
