Months after launching its streaming audiobook service in the U.S., U.K., and Australia, Spotify reported that users have accessed roughly 90,000 titles, with Britney Spears’s memoir The Woman in Me topping the list of most-listened-to books. Though reps declined to share more specific data, Spotify said in a release that the company has paid out “tens of millions” of dollars to audiobook publishers and that the “early results” show that the company’s audiobook streaming service “is driving a meaningful incremental revenue stream for the publishing community.”
