Undersound is a new project to distribute music around the London Underground trains. Users can upload songs from their collections to centralized distribution points, and download tracks left by other users.

Not all subways are created equal. What if technology designers recognized this fact and attempted to create an interface that took a deeper look at what being mobile means to each of us? What if they tried to reflect and enhance your sometimes conflicting, but always meaningful and situated, experiences? What if they designed for your underground? They did. They created undersound.
