Spotify has introduced a paid subscription plan focused on audiobooks in the US. For $9.99 per month, the Audiobooks Access Tier allows users to listen to 15 hours worth of audiobooks. Music and podcasts remain ad-supported, like a free account. (That’s one dollar per month less than Spotify’s Premium plan, which includes 15 hours of audiobooks along with ad-free music and other features.) “Spotify offers several subscription plans tailored to fit a variety of users’ preferences and will continue to invest in giving our listeners more options to cater to their unique needs,” the company said in a release.
