FamicomBox was used for display systems for the Famicom in various shops in Japan. It is similar the M82 (NES) that Nintendo used in America, in that the unit holds several game cartridges inside it, all of which can be accessed at any time.
It's interesting that the unit has any music of its own. Akito Nakatsuka composed a few tracks for the system. However, two of them appear to be unused.
Akito programmed the music in 6502 assembly language. The game appears to use the same sound driver as Super Mario Bros. (NES). However, it is unknown if Akito programmed the sound driver, Koji Kondo, or any other Nintendo personnel.

If it's not surprising enough that the FamicomBox has some of its own music, the game also has credits. However, they are hidden and require a cheat to access them; turn the key to position 6, then in the debug menu, press Up, Down, Left, Right, A, B, Select, and Start. You will then be brought to the credits, in which you may press Select to look through them.
Ripping NES music is an arduous process that is beyond the scope of this site.
