I had a stream of myself playing piano auto-muted due to an erroneous copyright issue. I was performing Mozart's Sonata in C Major and Mozart's Fantasia in D Minor, and the copyright conflict was for other artists' rightfully copyrighted performances, not for the piece in question that I was performing.

I'm betting that the auto-mute algorithm could be smart enough to know when somebody is performing a piece vs playing from a recording.

Until this is fixed, this feature will disproportionately affect musicians using Twitch to perform works that are in the public domain.
