[thanatropism]

Anecdote applies to me.

I experience some headphone fatigue nowadays too. Once upon a time I must have been listening to music for 60-75% of my waking minutes.

Also somehow I feel much more tranquil in just walking and listening to my thoughts and feelings (even unwelcome ones). I think I listened to a lot of music to experiment with different identities and ways of feeling, and approx. since I turned 30 I started to develop my own in a much more interesting way.
