As I watch the wallpapers of Linux Mint 17 cinnamon I wonder. What is the music that goes along with these images? This gives me the idea that each Linux distribution release could have its own music. A small playlist of creative commons music. I think relaxing, acoustic or very good audiophile recordings are a given choice. Then you probably would want a dedicated way of playing these. Here I'm thinking of a simple toggle button on the panel and a fast key.
Maybe this could further enhance the Linux experience.
