Spotify will fail unless they make their UI more than a simple streamer for podcasts. They don't have the capacity to stream video+audio and JRE (joe rogan exp) has been glitchy and sometimes unwatchable (there is no way to turn off video at this time). There is no ability to catchup on a podcast (or bulk mark them already played). The ordering on the app is newest to oldest (sorting the other way makes the UI upside down, next should be the newer). On and on, the usability features are just not there yet and any semi-decent RSS player is more than adequate.
To suggest they are going to charge for it when they have done almost nothing to make it comparable to existing podcast app is a joke.
I use spotify for music and mostly it's ok, but the app on android, windows and browser struggles with video. The JRE mess is causing me to look at amazon and google for music.
