A Music Panel is one of the two objects with the ability to change the music playing in a room. Music Panels are located in all of the Atrium rooms and the Government Lab. It can be used to play either the regular music that comes with the game or music which you've created using the Keyboard in either the Sax or Lion Lounge. There are none located outside of the hotel, only an XAM Satellite Stereo in the Saloon, another object used to change music.
