It's great that you're writing about this; the world is already filled with sounds, from birdsong to street noise. Actually, our world is too loud. It gets more bearable in the city in the evenings after 9 p.m., and I almost always listen to music or podcasts in the background, drowning out the outside noise. It's certainly good for your brain/soul to listen to less music.
