Music vanishes from Earth, and suddenly the world loses color without anyone noticing why. Doraemon and the gang have to remember what silence cost them before it's too late. Every scene moves to an invisible beat you didn't know was holding the whole movie together, and the soundtrack doesn't just underscore the story, it IS the story. The pacing stumbles when the plot stops to explain itself. Still, this hits hardest for anyone who's ever had a song save them without knowing it was happening.

Music is so woven into everyday life that people rarely think about it, but what if it disappeared from the earth? Doraemon and his friends set out to rescue the planet from a crisis built around that idea. The feature is a wholly original story rather than an adaptation, and it is the forty-third Doraemon movie. It mixes adventure, comedy and science fiction with a strong musical theme.
