SC rules says that you couldn't include any content with copyright that you don't have any permit/license to reproduce. That includes spotify/youtube/whatever.
However, I don't think SC platform is analyzing streams in real-time.
Twitch is dealing with general licenses for years and still get nothing, but, they're trying to get legal permits so streamers in Twitch could stream with music legally.
What some Twitch streamers do is to stream with whatever music needed to get engagement (commercial music basically), and as soon as they finishes the stream, delete the video.
Twitch is not analyzing live streams in real-time neither.
YouTube is a bit more complicated. They do have lots of options and licenses, so you could have a video posted with copyrighted music, making no money, and played showing the copyright licensee details below. But that depends on lots of things that I really don't know.
Also YouTube analyzes live streams on real time, and also on published videos. Same for Instagram and Facebook.
Most of those big social networks do have a 3-strike policy. So if you ignores the copyright, your account could be banned, and that is a big problem.
So, my opinion: you may get in "trouble" on sfw social networks.
You don't have permission to stream copyrighted content/music without a license/permission. On camsites neither. (and you should'nt). But if you do, be carefull to not keep any video saved anywhere.
Wanna do stream music legally?
Here there's a lot of information, licenses that costs hundreds of thousands, differnet types of licenses, licenses depending on how much tiem you'll stream music, and what countries will be listening to it.
The good thing is that some people realized that streamers needs an easy and affordable solution to stream legal music.
I spent so many hours investigating (I'm considering to stream music on Twitch), and that's a good solution:
35.000 tracks royalty-free on the catalog you may use for your commercial activities (streaming).
