But he already explains why it won't work at the beginning. If stuff is cataloged according to a pop paradigm, why would we expect to be able to reassemble it according to a classical one?

Presumably a pop DJ would also mess this up. It's like going to an Indian restaurant and asking what Dim Sum they recommend.

The only reason a human would be able to do this task is that they might be trained in how to find classical music, and they have spent some time learning what is what in that world.

But a Spotify AI is of course going to be trained on the prevailing classification system only.

The whole pitch of AI is that the model is going to be able to make exploit general knowledge outside of the local scope of the problem, just like a human would do. So I would also expect that it would be able to transfer his knowledge of classical music learned in language training, and apply that to the Spotify database.

The classical classification system is equivalent to the classification of cover versions in popular music. Of course, most audio software handles cover versions poorly too, but it's not like it's a completely unknown problem.
