This made me think of all the copyright claiming against classical musicians performing pieces for the sound recording copyright (rather than the piece itself being copyrighted; so many pieces are out of copyright in a significant number of places[0]). I don't use youtube so I'm not sure if it's still a thing that happens? If it is, I wonder how this eraser tool will behave. Would a few bars of someone's performance of a piece be removed because there's inevitably going to be similarities when performing a piece? [0] imslp.org is a great source for pieces no longer under copyright. Not all the sheet music itself on imslp is out of copyright in all jurisdictions, of course.
