Just to add on (if you are part of an FC or will join one in the future):

If you have permissions to select the song playing in your FC house's orchestrion, you will see the same list as what you have unlocked. Same goes for all other individual players in your FC. Why this is important to note is because if you'd want to hear something that's *not* on your list but someone else has it, they can select it (if they have the appropriate FC permissions) and you will be able to hear the song in your FC house.
