So, let my clarify: I recorded a live performance of my students on a stage in my city, it was all indoors and PRIVATE, no one from the outsidce of the school saw this, and I never planned on releasing the vids publicly, of course. Yet, some damn ROBOTS obv claimed my videos, 3 out of 7 were blocked, the rest copyrighted on the spot. BECAUSE THERE WAS MUSIC IN THE BACKGROUND. ... yeah. Youtube has gone completely nuts. That is just beyond ridiculous right now. HUGE HUGE L.O.L. and f*ck you to people who gave such 'powers' to lawyers, instead of protecting FAIR USE.
