In Theatrhythm Final Fantasy: Curtain Call, if you can assemble a party with sufficient damage sustainability, it is possible to clear a stage without doing anything. This will yield 0 points of score and 0 EXP. However, this could be a good way to grind for Rhythmia, by playing The Airship (FF4, with as many FF4 characters as possible), or Chocobo Theme (FF2, DLC, the shortest song).
