What do you listen to when you code?
mlok: Techno / electro. These often have the energy and rythm of machines, and it helps to keep a good pace.
I especially avoid any music with lyrics in a language I understand, so it does not steal my attention.
All in all, I want my surrounding to be an atmosphere of "going forward" and no distraction.
I also need to regularly look away from my screen, release my brain for a minute, get up and stop being static.
