Not too long ago I finally gave podcasts a try. For a while I was hooked. Most importantly, in Spotify it was trivially easy to increase the speed from 1x to 1.25x and 1.5x. After a while, for certain sections I could listen at 2x and still understand everything, and it was much more engaging! As long as I could control the playback speed, I think I could get into audio books, too (though I haven't yet. My commute is short...)
