How The Economic Machine Works by Ray Dalio comes to mind. It's 31 minutes long and provides a great high-level overview of basic economic principles.
I also listen to old tool restauration videos/CNC/industrial sounds as they put me to sleep as fast if I haven't booked a hotel room on the first floor of a hotel that gives to a busy city street at peak time, or at a specific place that overlooks a mechanic shop with pneumatic tools during work hours. I can't control traffic or people's work hours, so these videos are the closest I got to reproducible, predictable, on-demand sleep.
