Many of the songs we sing to our children are hundreds of years old, with their original meanings obscured by history. In this episode, producer Leila Battison takes Dallas on a dark, surprising journey through history’s most famous nursery rhymes and lullabies, and up through the “Baby Sharks” and “Happy Songs” of today. Along the way, they share the songs they’ve made up for their own children, and explore why this music is just as important to parents as it is to kids.

Whale songs are some of the most beautiful, cathartic sounds in nature. These extraordinary creatures use sound to socialize, to mate, to find food, and avoid predators. But for aquatic animals, the sounds of human activity can be absolutely devastating. With underwater noise pollution on the rise, what can we do to ensure the survival of these amazing creatures? Featuring acoustician Al Jones, Professor John Hildebrand of the Scripps Institution of Oceanography, and Vox Senior Producer Christophe Haubursin.

Today, that little sound is being heard millions of times a day on apps like Instagram, Reddit and Youtube… but creating it wasn’t easy. To make it, the creative team went through thousands of iterations, executed a covert marketing strategy, and fought through a final debate about a single note. Featuring Roscoe Williamson and Aifric Lennon from MassiveMusic.
