The black sheep of the Bust a Groove series. Only released in Japan, its got some design quirks that makes it harder to play compared to the previous games. This one focuses on dancing as a team also. Personally wasn't digging the OST much at first, it did grow on me as time went on though. Character designs from Hideyuki Tanaka that makes you want to instantly sit down and draw, as much as the game makes you want to stand up and dance.
