Sibling comment is correct. What I meant is I don’t listen to music/podcasts by default: when I walk, I walk in silence. I don’t use audio as background noise.

Instead, when I listen to music, it’s usually by sitting down deliberately to exclusively listen to music. The music isn’t idle background noise but rather the point of that activity. I enjoy music a lot more now, I find.

In general I try to have silence where in the past I would have had audio playing in the background. So definitely while walking but also while working (since I’m working from home and don’t need to drown out office noises).
