IMO Spotify's app both desktop and mobile are so much less of a headache to use over the AMZ Music app.

Spotify is improving podcasts as well. Something that they've just started doing is including auto-generated chapters to help you find a particular section of a podcast you might want to revisit.

But it is also cool that they've started including audiobooks in their subscription as well. I recognize it is limited to a relatively small about of hours but it's still a welcome feature.
