You can't play Bach on Facebook because Sony says they own his compositions
I have to wonder - isn't the response to this kind of ridiculousness to simply not post on YouTube, for example: <a href="http://allofbach.com/en/" rel="nofollow">http://allofbach.com/en/</a> ? Yes it's not going to get you the audience YouTube might, but if their platform isn't serving legitimate artists then what good is it anyway?
