Spotify Premium now includes 15 hours of free audiobook listening for U.S. subscribers. If you exceed your monthly 15-hour limit, you can purchase an additional 10 hours of listening for $12.99. Unfortunately, subscribers on the Student plan are ineligible for this perk. And if you’re on a Family or Duo plan, only the Plan Manager will receive full audiobook access.
