Polyrhythm (song)
# Polyrhythm (song)

"Polyrhythm" (ポリリズム, Poririzumu) is a song by Perfume, released as the second single from their second album Game and 10th overall, as well as the first track on their third compilation album Love the World. Appropriately, the song's bridge is polyrhythmic, incorporating 5/8, 6/8 in the vocals, common time (4/4) and 3/2 in the drums. Tokuma Japan Communications originally requested for the bridge of the song to be removed for its atypical nature; a concession was reached by including a radio edit known as the "Extra Short Edit" on the single, which removes the bridge while the vocoded backing vocal on the near-end of the song (at 3:02) is half-distorted. The song was used for the Kankyō Recycle Campaign by NHK. The single has two editions: a CD only version and CD+DVD version. The only difference between the CD and CD+DVD version is that the CD+DVD version features the music video.

"Polyrhythm" appears in Konami's Dance Dance Revolution and Pop'n Music arcade music games (covered by Pink Lemonade), as well as Namco's Taiko no Tatsujin. Former Megadeth guitarist Marty Friedman also released his own version of the song on his album Tokyo Jukebox. The song appeared in the film and soundtrack for the Pixar film Cars 2. The director, John Lasseter, said "The moment I listened to Polyrhythm, I loved it, it was like falling in love."
