What do you listen to when writing code?

Listening to music usually increases my productivity when I deal with the layout part of an app (everything related to HTML, CSS) but I can't really focus if I need to think about functionality/ write Javascript. The absolute no-go is listening to German lessons while writing any kind of code.

What are your listening habits? Are you going for music, podcasts, audiobooks? Feel free to share any of those (maybe some of us will also find inspiration in the things you listen to while writing code; plus, I ran out of new music :D).
