I find that if I'm driving or doing a chore or something, listening to nothing can sometimes be boring, but if I listen to a podcast I'll sometimes get distracted by my own thoughts and miss 5 minutes of it. Music tends to be the sweet spot in the middle where if my mind wants to wander then I'm not missing anything important, but if my mind doesn't want to wander then I still have something for it to focus on.

Being bored is kind of the point though. You should let yourself be bored sometimes. It's a relatively new phenomenon where we have completely avoided any minute of boredom.

Similar for me but I actually like podcasts in the car for this reason. Listening to podcasts sometimes triggers me thinking about issues I care about. When I realize that I’m no longer following the podcast, I just turn it off and let my thoughts go wild.
