The music for the MMORPG Final Fantasy XIV was composed by Nobuo Uematsu, a regular contributor to the music of the Final Fantasy series. Several other composers including Masayoshi Soken and Naoshi Mizuta contributed music for updates to the game. The music for the game's reboot, Final Fantasy XIV: A Realm Reborn, and subsequent expansions, is compiled of a collection of original and remixed songs by numerous composers, namely Uematsu, Soken, as well as others including guest composers such as Okabe of the NIER series. Soken was the sound director for both releases of the game. Music from both releases of the game has been released in several albums. A pair of mini-albums containing a handful of selected tracks from XIV, Final Fantasy XIV: Battle Tracks and Final Fantasy XIV: Field Tracks, were released by Square Enix in 2010 when XIV first launched. A soundtrack album titled Final Fantasy XIV - Eorzean Frontiers, containing most of the music that had been released by that point for XIV, was digitally released in 2012. A final soundtrack album for the original release of the game, Before Meteor: Final Fantasy XIV Original Soundtrack, was released in 2013 just before the launch of A Realm Reborn, and contains all of the music that was composed for XIV throughout its lifetime. The latest soundtrack album, Shadowbringers: Final Fantasy XIV Original Soundtrack, was released in 2019. This album contains the music for the third expansion, Shadowbringers, and music from the previous expansion, Stormblood, that was added to the game via patches after the release of that expansion's soundtrack.
The soundtracks for both releases of the game were well received by critics. Uematsu's mix of orchestral and rock tracks for XIV were praised, though the delayed release of a full album drew criticism. Soken's work on A Realm Reborn, including both his original tracks as well as themes carried over from XIV and previous Final Fantasy games, were heavily praised by reviewers for the game. Music from the initial release of the game has been played in the international Distant Worlds Final Fantasy concert series, and books of sheet music for piano arrangements of music from the game have been produced.
