I think a lot of you guys are familiar with the movie called Inception. I chose this track, because it represent the flow of a big city so well. In the beginning it is slow, and keep going, but faster and faster. At the end, there is the big boom, when everything is done, and nothing to do anymore. And there are some nice effects in the movie, for example when Cobb and the girl just rotate the streets of the city, and after it walk upwards!
I'm building cities in my mind while listening to this. Good Choice!
