The vast majority of gaming companies don't even give you the license/right to stream their games, but are happy to accept it because of the marketing opportunities that brings. Though that could change at any moment, and there's certainly been cases in the past where developers have gone after streamers under DMCA for reasons or no reason, and it's entirely legal.
Firewatch creators can target PewDiePie with DMCA takedowns, and it’s perfectly legal

The RIAA certainly aren't seeing any marketing opportunities from the use of their members content, and quite understandably want to be paid.
I mean, I understand how it's developed, but no one would bat an eyelid at a streamer getting hit with a DMCA takedown if they were just playing Metallica's DVD of Live Shit: Binge and Purge, but you slap a game over the top and everyone thinks it's fine and Metallica have no rights anymore? That it's sufficiently transformative? It's a weird situation to be in.
Are you a member of the RIAA? I don't see how that's a reasonable take. Just because a company owns a song that shouldn't mean that are able to bully and cajole everyone else to pay for them money for every existence of the those sounds and that shouldn't mean that their song rights supersede everyone else's. Someone plays music in the background while your streaming, they own the whole content. We're basically at the stage where the RIAA owns sound waves, which is way beyond what copyright was intended for.
It basically is rentiering of soundwaves, 🤔, we really are close to the end game of capitalism. The companies "struggling" for revenue sit on these assets perpetually, and look for more ways they can gain revenue from them and they don't create much new content and stifle others from creating new content.
