Final Fantasy VII is a role-playing video game by Square (now Square Enix) as the seventh installment in the Final Fantasy series. Released in 1997, the game sparked the release of a collection of media centered on the game entitled the Compilation of Final Fantasy VII. The music of the Final Fantasy VII series includes not only the soundtrack to the original game and its associated albums, but also the soundtracks and music albums released for the other titles in the collection. The first album produced was Final Fantasy VII Original Soundtrack, a compilation of all the music in the game. It was released as a soundtrack album on four CDs by DigiCube in 1997. A selection of tracks from the album was released in the single-disc Reunion Tracks by DigiCube the same year. Piano Collections Final Fantasy VII, an album featuring piano arrangements of pieces from the soundtrack, was released in 2003 by DigiCube, and Square Enix began reprinting all three albums in 2004. To date, these are the only released albums based on the original game's soundtrack, and were solely composed by regular series composer Nobuo Uematsu; his role for the majority of subsequent albums has been filled by Masashi Hamauzu and Takeharu Ishimoto.
The Compilation of Final Fantasy VII began eight years after the release of Final Fantasy VII with the release of the animated film sequel Advent Children in 2005. The soundtracks for each of the titles in the collection are included in an album, starting with the album release of the soundtrack to Advent Children that year. The following year, Nippon Crown released a soundtrack album to correspond with the video game Dirge of Cerberus, while Square Enix launched a download-only collection of music from the multiplayer mode of the game, which was only released in Japan. After the launch of the game Crisis Core in 2007, Warner Music Japan produced the title's soundtrack. The latest album in the collection, Before Crisis: Final Fantasy VII & Last Order: Final Fantasy VII Original Soundtrack, was released by Square Enix the same year as a combined soundtrack album for the game Before Crisis and the animated movie Last Order.
The original music received highly positive reviews from critics, who found many of the tunes to be memorable and noted the emotional intensity of several of the tracks. The reception for the other albums has been mixed, with reactions ranging from enthusiastic praise to disappointment. Several pieces from the soundtrack, particularly "One-Winged Angel" and "Aeris' Theme", remain popular and have been performed numerous times in orchestral concert series such as Dear Friends: Music from Final Fantasy and Tour de Japon: Music from Final Fantasy. Music from the Original Soundtrack has been included in arranged albums and compilations by Square as well as outside groups.
