ITT: The song you listen to when you're writing: https://www.youtube.com/watch?v=em30XL9c5NQ
I make playlists of chill songs or disco/soul songs that can put me in a trance. You want it good enough to pay attention to if your mind wanders but enough to tune out if you're in the zone.
Sounds like crystal castles. All it's missing is a girl shrieking over it.
