I'm with @Elena and @StatenIslander on this one. In wilderness, I'm disinclined to listen to anything, generally. In settled lands, I'm all about the audiobooks, dozens per year. I find that music makes me too hyper-aware of the rhythm of my steps vs. the music. And in hilly areas or when I have to adapt to roads/traffic/other humans, my pacing is never going to be consistent to a beat.
