"Music tames the wild beast." It also gets the creative process moving when you find yourself trapped in a bind. Something about the delicate rhythm (or lack of rhythm) appeals to the imagination - with or without the influence of lyrics.
Whether I'm working-working or working on my speculative writing, silence is NOT an option. I have to have something in the background to keep from going up the wall, and music fills the void for me. What I choose to listen to depends on what I'm working on, and my go-to playlists raise some eyebrows.
