These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Mind Screw: One of the songs on the arcade version is the infamous Pon Pon Pon. Thankfully, they exorcised the music video, but god help those who're curious enough to look up the PV on Youtube...
However, the game is straight up mind screw to those who have not heard of the Kinect, let alone know how to use one.
Soundtrack Dissonance: "FLOWER" doesn't sound like something you would put in a game with a heavy emphasis on dance routines, but it was put in anyway because of Konami's habit of crossing it over into every active BEMANI game.
Polished Port: DanceEvolution Arcade, if only for its continous addition of new songs.
