TikTok’s sonic logo is one of the fastest growing sonic logos in history. 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.

If you listen to vintage music, one of the first things you’ll notice is the complete lack of bass. But turn on a Top 40 station today, and you’ll hear song after song with deep, sub-ratting bass tones. So how and why did this change happen? For this episode, we worked with OnePlus to tell the story of our collective obsession with bass, and the one device that transformed the sound of popular music. Featuring hip-hop legend DJ Jazzy Jeff and Roland's Paul McCabe.

For more than three decades, it was common for American companies to put on “industrial musicals” for their employees. These elaborate productions could rival Broadway shows, and featured original songs about the company and its products. And while this music was never intended for the general public, once you hear it for yourself, you might just get hooked. This is a story about bathroom remodeling, corporate art, and one man’s obsession with a forgotten corner of pop culture. Featuring comedy writer and collector Steve Young.
