To some extent yes. Some games gain more popularity because of streaming. As for playing music, that's a tad bit different, because you're not advertising the music like a streamer would a game. Among Us is like a murder mystery game. You can play a max of 10 players per game, there are crewmates and impostors. Impostors are tasked with killing the crewmate, and can also sabotage areas on the map. Once a body is found, you're brought into an emergency meeting, where each surviving players have to discuss who they think the impostors are. This game came out in 2018 without much fanfare. But, due to some streamers showcasing it recently, it blew up and now the dev is working on adding to the game again. Watch a stream of it if you can, it's pretty much made for streaming.
I'm just going off of gameplay I've seen. People seem to really enjoy it though, so maybe it's a fine game. But my point still stands, it's helping these unknown games become a lot more popular. Developers know full well about it and happily go for it. Because it helps that game sell.
Even so, bad games can be good depending on who the person is. Minecraft and Fall Guys are well made games that take minimal effort to get into. You may find them to be terrible games, that doesn't mean it's so. I've played a lot of games I thought to be bad, but a lot of people end up enjoying them. It's all subjective. One bad game, could be a fun time for a group of friends. As long as people enjoy it, who cares.
And that's fine. Keep in mind though, a streamer can still stream a game, as long as they add commentary and make it transformative. What this means, is that they have to build upon the original content and add to it. Add their opinions, such as a review, or add their thoughts on the game, etc. That's considered fair use, since they're discussing it, making it transformative. I would understand if a streamer just streamed the entirety of a game without adding any commentary around it, but most streamers don't do this.
Keep in mind though, that most developers and publishers want people to stream their games. It does help sell games a lot more than standard marketing does these days. And sure, some bad games might be in the mix, but that's to be expected.
I have to disagree. Most streamers I've watched add a lot to the table, either it be from fan interaction, commentary, and free promotion of course. Streamers don't just sit there and play a game. If they did that, no one would be watching their streams.
