There are a bunch of twitch's own show vods that are muted due to this system. Holy shit the irony is real.
This is honestly the worst way this could have been done. There are a lot of bigger streams that have paid for the licences to play certain music, and they are still going to get hit by this because their system doesn't take that into account. The streamer has to dispute every single mute if they want their vods to be seen. It's bad enough that videos of games with music in them will be muted, but the fact that streamers are going through the legal route and paying for the right to use this music and still have to fight this new system is insane.
