You can see from the fingerprints that they are all different. It also
seems obvious that 083eb0a7-0d6e-44a9-99b0-f2232568ffcc is actually the
the Mozart recording. Since the others are different, they obviously
aren’t. Assuming they were entered in good faith (always a good idea),
they must each belong to the other recording, since they each only have two.
Just unlink them from the Mozart recordings, and leave them attached to
the other. If someone comes along and finds out otherwise they can
always unlink them too.
