So far you have done a perfect job sticking to "canon" as it were (though I can be very lenient with that if persuaded), so no worries on that front. You can also introduce your own stuff to the RP (like LHG has done with his food stuff), and unless it actively disrupts the flow of the RP I won't mind it. You can leave the door open to the music room, and there is indeed a window to the room.
