On a typical commute into downtown Portland, an activity that typically eats up to two hours per day, I could catch up on some Z's, listen to music, something else relaxing, or learn something new via podcasts. Apple's Podcast app is one of the best default installed apps I have used.
I get burned out on genres and I almost never listen to the same podcast episode twice, unless I happened to have fallen asleep and forgot what happened in the podcast. These are sorted in order of what you should listen to first before the others. Not everyone that I admire from their non-radio works is good at both podcast scripting for audio listeners and are a good podcast host. These are just suggestions of what I think make for pretty good commuter listening.
