I am bored by hearing old GD music
i want to play some new music
is there a way for me to change its BGM? is there a mod or some tools for me to do this, and is there any cool music you think is good for GD?
many thx 
Easy. Turn off game music, turn on any radio you like in a player or a browser.
I often listen to Lovecrafts audiobooks on youtube while playing, maybe that’s something for you aswell?
