Is it really a bad idea to make a FC/shared house's Orchestrion sheets shared?

[Niwashi]

Having each character collect their own has three advantages that I can think of:

• As Velox mentioned, you only need one copy rather than 3.
• Collectors have something to collect. Their game isn't appropriated by whichever FC member got to it first. (Though if they still had a collection to gather for the inn room, maybe this part doesn't matter.)
• It adds a social aspect to the orchestrion, that you can gather together in your FC house and share your music with each other. If all the music your FC has access to were just there, without any need for the provider of that music to play it, then it loses that interactivity.

To counter those, there's the disadvantage that you have a more limited assortment of music you can play (at least until you manage to expand your own personal music library).

I can see different players preferring either way, but overall I think I agree with SE's decision on this design.
