I feel like a fun addition would be adding sheet music to the game that players can find in various places. If another player happens to have found the same song as you, they can join in. Good for camaraderie and enjoyable moments in my opinion.
SONGS AS ITEMS
I agree with finding songs but not as a random thing... amybe island theme music sheets would work. It would be great to have a sheet music load out where you can choose the music you want to play. I'd love to play the pirate legend "we shall sail together" song whenever I want instead of having to go to the tavern for it
