I tried audio books on Google play and was positively surprised. Great UX ... I can cast to my Chromecast audio, I can add a shortcut to resume my book with one click on my phone. It integrates with Google assistant, easy chapter navigation, easy to manage downloads... Everything just worked better than expected. I had a past experience with audible that was far from great. I ended up cancelling my subscription and mostly forgot about audio books, mostly because of UX. Now I'm hooked again.
Prices were also pretty low, although I think they were running a promo because it was a new service.
I don't think they have a subscription model though. It's a pay per book kind of thing. I prefer this way because with the subscription I always felt like I was missing out if I didn't listen to at least 3 books. But there's value in having a subscription model.
Curious if someone have experience with other audio book ecosystems
