I'll have to go through and see what is missing now.
I have an editorial comment on this subject. Coloraturafan has been removed from YouTube due to copyright violations. Obviously, if you buy a commercial video, bring it home and upload it to YouTube, that is illegal. Emphasis on the word commercial. If you capture something from a stream, is that illegal? Who knows?
If you are strictly literal, absolutely everything that you didn't film with your own camera and then post to YouTube is illegal. And even that might be illegal if you are filming someone or something that is otherwise covered. In these two sentences we have covered all the classical music on YouTube. If you film yourself, you're good. Would I want a film of myself? Probably not. I notice there's an old woman who films her blog.
YouTube allows samples, supposedly. I am unaware that coloraturafan posted anything but samples. Recently I know he posted items from the Il Trovatore stream from Munich. I know this because I linked to a couple of them. When asked, he took them down. The usual reason organizations ask that a film be removed is because they decide to make a commercial video of it. If they decide not to, they let it go. I won't cite specific instances. How is someone to know this before the fact? And why should someone be punished for something they can't know?
I think the world of classical music needs all the exposure it can get.
