This is my third 'music thread', and yes, I do listen to music while typing.
Depends on the mood, or the scene. If it's a battle scene, or I wanted to stay focused, I listen to rock especially Sabaton (I also get to come up with ideas for the scenes I wanted).
If I just want to spit out words for first draft, I listen to lo-fi.
If I want some diversion from the background noise (since I live with my parents), I go for anime music or OPM.
