Rhythm Heaven

"Rhythm Heaven, known in Europe as Rhythm Paradise and in Japan as Rhythm Tengoku Gold (リズム天国ゴールド, Rizumu Tengoku Gōrudo, lit. "Rhythm Heaven Gold" or "Rhythm Paradise Gold") is a rhythm video game for the Nintendo DS handheld video game console. It is the sequel to the Japan-only Game Boy Advance title Rhythm Tengoku.
In Japan and PAL regions, the game is published under the Touch! Generations brand. It also has an iTunes visualizer at its official website.
Rhythm Heaven has the player tap, flick, and hold the stylus on the touch screen to make a beat to match the background music for the level. The Nintendo DS is held on its side like a book with the top screen on the left and the touch screen on the right (vice versa in left-handed mode)."
