For those unaware, it's possible to use alternative clients for Spotify using a 3rd party daemon.
Fun fact, AFAICT the fastest growing major podcast platform is re-uploads of podcasts to youtube. Which makes no sense on most mobile platforms, but at least the visibility of entries to the public will be high.
Why? I watch a lot of podcasts on youtube, it's interesting to see the interaction, so the visual component is not a negative.
In fact, the vast majority of podcasts I've heard aren't audio-only. The only one audio-only ones I've listened to are the old Opie and Anthony show uploads.
