Best off replacing the music. Even if the creator of the music is fine with you using it, the right's holders usually don't bother - and you'll get automatically content ID's on Youtube, or VOD muted on Twitch,
I thought so as well.
Thanks for getting back to me and good luck.
but how do you replace the music? (the in game Music)
kinda complicated.
You'd first have to extract the .exe itself, and then use a method of extracting the data.win file, and repacking it sans-music.
