It’s a music fan’s dream: Imagine you’re handed hundreds of hours of never-before-heard tapes of Paul McCartney talking about all the lyrics he’s ever written.

Those tapes showed up on the doorstep of one lucky team of podcast producers. McCartney: A Life In Lyrics is a new podcast telling the stories behind the lyrics of some of McCartney’s most famous songs, from the early days all the way to the present. Leah sits down with executive producer Justin Richmond to talk about the project.

Then, Leah talks to Laurie Santos, host of The Happiness Lab, about collaborating with Elmo, Grover and the rest of the Sesame Street gang to teach kids about the science of happiness.

All that and more, this week on Podcast Playlist.

Featuring: McCartney: A Life In Lyrics, Rough Translation, The Happiness Lab, Academy
