See my sibling comment.

Yes, if the owner uploads somthing to yt and\or if the composition in public domain - it will be there. But that's it.

For example you have Netherlands Bach Society on Youtube. And I most likely can upload a rare Chaliapin's recording.

But:

- this one big "IF".

- this won't work same way for some rare Michael Jackson composition, for example.
