When I’m coding, sometimes I’ll put on various game soundtracks on Spotify.
I don’t listen to soundtracks for games I already play. I know the music too well and it’s distracting. I focus on trying out music from stuff I’ve never played.
Besides getting music that helps me focus, as a bonus I end up discovering interesting games I’d never heard of before and probably wouldn’t have found any other way.
It’s pretty awesome, though it does mean my Steam wishlist gets even longer.
