 Spotify announced Tuesday that it will now offer audio books to Spotify premium subscribers at no additional charge. Starting in Australia and the UK with other markets including the US getting it later this year. Around 150,000 books, that's about half of what they have in the catalog, you can only listen to 15 hours of those books per month, after which you have to wait until next month or purchase extra 10 hours in blocks of 10 hours, which most of the books I read are more than 15 hours, so I'm not sure how this is going to go down.
