What music sets the speed/tone of the development? I know most people like trance/techno/classical (stuff w/o lyrics). Nectarine is also an option (old tracker music).
I find I code faster with "hacker"-music like for instance the ost to Pi; http://open.spotify.com/album/5C0sEGbStaD8ZWQzBrNxJ3
What's the ultimate hacker music? Has anyone made a hackertunez play list generator?
