If you're a fan of Final Fantasy and the music that makes each game so iconic, you'll be pleased to hear that most of the games' soundtracks have arrived on both Spotify and iTunes. The collected works of Nobuo Uematsu and other artists are all available and include all soundtracks from Final Fantasy I through FFXV. In addition, a number of other Final Fantasy games are also included such as FF Tactics, Dissidia Final Fantasy and others.
You may remember that in Fall 2018, Nobuo Uematsu wrote that he would be taking an indefinite hiatus from composing due to health issues including fatigue. "I find it mentally and physically difficult to go at my current pace."
