An ordinary audio player which only plays music by pressing a hotkey: "menu" (you can change it)
Warning
You need to install these following dependencies: just_playback and keyboard
You may ask "why does it exist?". Well, imagine you want some custom music in the game you're playing. But you can't modify the game assets! And then you come up with a workaround that this script replicates. You hit a single key you don't press often, and the music you chose plays!! Just mute the original music in game settings.
