On the main Nano website, in the sprint section, there is usually a post about an epic hour long music challenge. The person posts a youtube link to instrumental music for everyone to write to. It works way better than I ever expected it too. It's usually movie scores or I think one year it was even video game scores. I'm not talking Mario. I mean like for Dragon Age or Mass Effect. I think I got more done in that hour than I ever have. I just can't do it all the time, sit still for that long.
