Database of Common Strikes linked to game library
Create a database of commonly struck games that links with Game library on the dashboard. Then have a warning that displays when a streamer changes category to a game that is commonly struck by the game's (or music creator's) rights holder(s) so a streamer is aware and ready to deal action AFTER or make plans before.
I know some games have copyrighted music so those games may get many DMCA strikes. Here’s a potential solution, or at least a potential action, to take.
For games and game companies that have high DMCA strike rates specifically, it’d be wise to provide a warning to streamers prior to their stream. The warning simply states that the game may potentially get them DMCA strikes and then incentivizes them to either choose other games to avoid causing any issues or mute the native game music entirely. An ounce of prevention is worth a pound of cure. The warning can be per stream or a consistently updated public list. There are many options. This is also an option that gives power to content creators.
Also specifically for games. Have a Twitch extension with partnered and Twitch approved music for a variety of game and game genres to replace native BGM. This can also work with a lot of the “partner with music labels” ideas being floated around.
