In Game Music should not be Muted since it's part of the Game already.
If a song is part of the game, it should not be muted. If you're going to insist to have the stupid DMCA filters in place in the first place at least have them set to recognize songs that are in various games so I don't have parts of my stream muted for songs that the game comes with.
I started streaming Fallout 76 and i found stupid that the music OF THE GAME has to get muted. does the thing happens if i want to stream Cyberpunk? or GTA?
