I'd like to say it is IC. I see no reason why the item and the music couldn't be. Sure some of the metal tracks might be a bit harder to justify because of the music genre and the lyrics that refer to the primals.
It might not count for much of an argument, but just because they are primal related is not necessarily wrong if we take a look at real life music. We have real metal about religions, the devil, disease, wars and other things (such as glorious Paladins).
If you look at it a certain way it doesn't seem all that different from writing a song about a primal or otherwise a dangerous and unpleasant place.
That all being said, I would probably not so easily say the music is related to primals, despite acknowledging the Orchestrion itself as a real thing.
