Nobody's claiming a magic bullet. Nothing you mention invalidates the idea, I think.
For the first part(the nature of the "hash"), there should obviously be standards to address these questions. An official recording could be identified by a hash of the actual recording in some standard format(e.g. raw wave files).
For distribution of score sheet and lyrics, those can be treated separately and have their own hash identifier according to their own standard.
The rest are philosophical and legal questions that are orthogonal to the technical problem.
The point of the suggestion, is to address the technical side of the problem.
Having an open platform where authors/copyright owners can hold public records of their copyrighted works and their distribution, and point to it as legal evidence, would certainly be useful, don't you think?

That's the problem: you're addressing the most boring and the least important part of the problem that has already been solved. No one in this world has any trouble tracking and attributing songs once a song's metadata is correct. And providing correct metadata is the entirety of the problem which you just glossed over as "philosophical and legal questions that are orthogonal to the technical problem". They are not.
