Chō (Tsuki Amano song)
Chō is the 7th major single by female J-pop singer-songwriter Tsukiko Amano, from her third major album "Tenryū". It was released on November 12, 2003, and reached a peak of No. 49 on the Oricon weekly charts, charting for 8 weeks. The song is a mixture of pop and heavy rock, containing a guitar heavy chorus and interlude. The song was used as the theme song of PlayStation 2 survival horror game "". The lyrics of the song tie in with the main themes of the game, and the PV was shot using similar imagery  to that seen in-game, including crimson CG butterflies, which can also be seen on the cover. The song was also included on "Catalog", Amano's "best of" album. "Chō" itself is filled with emotional vocals and is slow in tempo; following the tradition of her other singles, the B-side is a parody of the titular song and has more of a "pop" feel.
