"Music is a mysterious thing. Sometimes it makes people remember things they do not expect. Many thoughts, feelings, memories... things almost forgotten... Regardless of whether the listener desires to remember or not."
One of the reasons for Xenogears' enduring popularity and influence is a soundtrack full of classics.
- Stars of Tears, which was cut from the game. This FMV was complete and on the disc, but just not naturally encountered during the game. Originally written with Animated Credits Opening in mind, the AMV idea was later scrapped since it would take fifteen minutes just for the opening sequence.
- Stage of Death could easily be a boss battle theme in most JRPGs. In this one? It's the standard battle theme.
- "Small Two of Pieces", the wonderfully cheesy Power Ballad that closes out the game. The Orchestral version of "Small Two of Pieces" is even more heartwrenching, especially when edited into the ending FMV. It is the first fully voiced track featured in a JRPG, preceding "Eyes on Me" by a year.
- For those who like darker themes, "Omen" in particular is something of a masterpiece.
- Flight since whenever that music plays, you know a Moment of Awesome is gonna happen. Even more awesome: It is the first (and currently only) Xenogears track to be featured on Theatrhythm Final Fantasy. Flight's softer and more emotional remix, Gathering Stars in the Night Sky, is more subtle and every bit as good.
- "Light from the Netherworld," the Background Music to the opening movie. Incredibly eerie and chill-inducing. Even if you've never even seen the opening movie, you can tell just by listening to it that something inexplicable and unearthly is going on. And now the Orchestral version is out, edited into the Opening FMV.
- Id's theme, "The One Who is Torn Apart." It can only be described as haunting.
- "One Who Bares Fangs at God" can ONLY be heard during the Anti-Climax Boss fight with Urobolus/Miang even though it's one of the best songs in the game. Which serves to redouble on the final battle's subversive principle — both the battle and the accompanying music are anything but the standard Final Boss fare, for dramatic purpose.
- "Grahf, Emperor of Darkness". When this comes on, it's obvious that either a boss is about to get a powerup or you are about to have your ass kicked.
- My Village Is Number One, a sound-alike of Chrono Trigger''s Millenial Fair that plays in Fei's hometown of Lahan. Then there's the orchestrated version, which bumps up the tempo to make it sound like a party is happening soon. Whether that's Alice and Timothy's ill-fated wedding at the beginning of the game or Fei and Elly getting their happy ending post-game is up to the listener to decide.
