I love audiobooks on Spotify. Unfortunately, they are currently accessed in very similar ways to regular music. They are organized in albums, there is an option to shuffle and there is no way of knowing where you stopped when you want to come back to a book.
Podcasts on the other hand, show you which episodes you've already listened to and the buttons Shuffle and Repeat have been replaced by "Skip 15 seconds". Those features would be great for audiobooks.
The change should be fairly easy to implement, since all the features are already in Spotify.

Your idea was submitted a while ago and unfortunately didn't receive the amount of kudos needed to stay active in the ideas board (100 Kudos per year).
In order to keep the Ideas Exchange clearer I'll close this idea for now, but this doesn't mean Spotify rejected this idea.
If you think this is an idea which needs to be implemented, you're welcome to post it in slightly different again 🙂
Have a nice day!
