I really love listening to the Donkey Kong soundtrack. It really has something that just relaxes you, or pushes you to the programming limits. It has tracks for every kind of mood. I listen to it on the train or when I travel to work to gain mental focus for the day. In the office, I switch to a different, more upbeat song to create tension. With passing time I switch to Donkey Kong songs with increasing tempo. My hands are literally flying over the keyboard and I am in complete balance with the code. Some of my coworkers say I'm "wired in". I wouldn't disaggre with that. At some point, when the evening is within grasp, I slowly decrease the tempo of my Donkey Kong songs to calm down step by step. On my way home I switch into chill-song mode again. During the night I let the aquatic ambience of Donkey Kong Country guide my dreams. Highly recommend it to everyone!
