Super Metroid: Sound in Action is a music CD released only in Japan. It was released on June 22, 1994 and features music from Metroid and Super Metroid. The Metroid music was composed by Hirokazu Tanaka and Super Metroid music was composed by Kenji Yamamoto and Minako Hamano, giving the CD a total runtime of 58:49.
The first four tracks of the CD are arranged versions of Super Metroid themes, followed by a fifth track that is an arranged version of Ending (Metroid). Remixed by Yoshiyuki Ito and Masumi Ito, these arrangements use higher-quality instruments than what the SNES was capable of producing.
The Metroid music appears to have been ripped from recordings of the Family Computer Disk System game and not from development files. Many of them contain in-game sound effects and do not contain the complete music track. The Super Metroid soundtrack is comparatively higher-quality.
