BGM collection quest idea

I've seen a lot of suggestions about having some sort of furnishing (ie. jukebox, etc…) for housing that allows you to change the music in the house or room.

I think it'd be pretty neat if it worked like the journal in the Inn Rooms. Except instead of collecting cutscenes, you'd be collecting musical tracks.

Going even further, it'd be fun if you had to do something in each zone to collect that particular zone's BGM. Like some sort of mini quest or something.

Just a thought!
