Playing only a single song just long enough to earn a copyright strike means this feature doesn't exist. Instead, it's an implementation of a checkbox on a settings screen that enables some side effects that are not what the text next to the checkbox describes.
It's not a crime. What criminal law is being broken?
Original music is created by the game creators and streaming rights are included in the software EULA.
Licensed music is created by third party artists and is usually not included in the software EULA because the music artist/publisher does not grant that type of license to the game creator/publisher. A gamer streaming gameplay that includes the copyrighted song will trigger automatic copyright protection on the streaming service they use and is subject to DMCA takedowns.
Modern games often include a "streamer mode" which replaces or mutes the licensed music.
In the US copyright infringement is unlawful but it's almost always civil law.
Can you point to the section of DMCA that you think turns this into a criminal offence rather than just civil infringement?
Doesn't that require having employees in, having facilities in, taking payments in or making payments to residents of said country?
Most of the streaming services this legislation is aimed at don't rise to that bar relative to the USA, as low as it is.

Twitch already has mostly DRM aware content creators - I hear them talking about 'rights' quite a lot in their streams.
It's the worst listening experience ever. It's much easier to just go to YouTube and listen to the song uploaded by an official channel.
