Podcasts
I've been surprised these past few months at how much of my non-music listening time (I listen to music on Apple Music and Prime Music), which had previously been spent listening to streaming radio is now almost exclusively spent listening to podcasts. There are so many good podcasts available now, on a wide range of subjects (and of course many more bad ones) that the average person can't possibly have the time to keep up.
There appears to be a sea change in listening habits happening right now, and I don't see much being written about it. I'll have more to say about this later, with a list of podcasts I listen to regularly.
