Blocks & Decoration Piano Changes

[DreadDreamer]

To the point:
A new Sheet Music item sold by either Merchant, Traveling Merchant, or Wizard NPCs. When used on a Piano, it changes the music currently playing into a piano cover of that song.
When Sheet Music is currently being used, the piano's sprite is updated to include it, and the appearance of the sheet itself changes depending on the piano (golden border/text on a golden piano, different shade of brown depending on the wood of the piano, etc).

If this has been done before, I am unaware of it, and apologize in advance.

What if instead of consuming a new item, it just plays a piano cover of whatever music box you place on it?

Your reply reminded me that I forgot to include something, sorry!
You would be able to remove the sheet music (think of it like an in-game bottle, a decoration item with a function) and replace it anytime you'd like. Although now that you mention it, a music box would probably be an easier and more convenient way to do it.
