[MuGen]

Cd/Vinyl still need to be read by magnetic laser or needle.

Merry-Go-Round is a good guess, and can work, but not the answer I'm looking for. But i'd imagine the music on the merry go round comes from a device that reads the music.

It's a music box. You open it up and the figure spins, and tuned platelets are hit by the turning gears inside to play a preprogrammed song. But it does not read something.
