''Xenoblade'' contains music composed by Creator/YokoShimomura, ACE+, Manami Kiyota, and Creator/YasunoriMitsuda (for the ending theme). [[SugarWiki/AwesomeMusic It works]]. We could easily list the entire soundtrack here. But if we get specific:
----
* The [[http://www.youtube.com/watch?v=PGkPEDFRgng Main Theme]]. It's used in-game during the WhamEpisode on Prison Island [[spoiler: when Fiora is revealed to be alive as a Face Mechon. The music is ''perfectly timed'' to what is happening on screen, reaching its crescendo just as Fiora turns to leave a confused and heartbroken Shulk behind. And to top it off? The main theme is a remix of Shulk and Fiora's shared leitmotif. It was ''made'' for that scene.]] This theme became an instant classic, and it's considered one of, if not THE absolute best tracks of Yoko Shimomura's in her entire career. [[VideoGame/StreetFighterII Let that]] [[Franchise/KingdomHearts sink in]] [[VideoGame/MarioAndLuigi for a]] [[VideoGame/WorldOfMana moment]]...
* [[http://www.youtube.com/watch?v=ifvuPEOWc6I "Time to Fight!"]] deserves a special mention. Yoko Shimomura keeps showing what she's made of.
* [[http://www.youtube.com/watch?v=0TXc5V8wKy0 "Hostile Gazes"]] and [[http://www.youtube.com/watch?v=MMrvVpD0zG4 "Enemies Closing In"]].
* [[http://www.youtube.com/watch?v=G_n9lMS3ahw "Mechonis Field"]].
* The [[http://www.youtube.com/watch?v=Hy0n5NXmgZo first prologue theme]] sets [[ActionPrologue the mood]] quite nicely, but [[http://www.youtube.com/watch?v=3B5I3frNnnw the second]] gets special credit by taking the Main Theme mentioned above and making a fast-paced battle remix out of it.
* [[http://www.youtube.com/watch?v=6Dy74NOzcS8 "Gaur Plain"]]. Good luck getting it out of your head after playing through the game. When the 3DS version was released, this track became the background music for the Nintendo eShop.
* [[http://www.youtube.com/watch?v=7OfNgkxkM_o "You Will Know Our Names"/"Those Who Bear Their Name"]]. It starts up whenever you fight a [[BossInMookClothing Unique Monster]], so when you hear it, asses ''will'' be kicked. Just hope that it's your party doing the kicking. [[spoiler:It's even more awesome when it plays against two storyline bosses who have been built up to be such assholes that you will feel such a rush kicking their asses: Mumkhar and Dickson, the latter being the ''penultimate boss of the game.'']]
** [[http://www.youtube.com/watch?v=KJsWEY6PGVQ Now available]] as an eight-bit remix. Somehow it sounds even more awesome.
** If Shulk were a {{Franchise/Pokemon}} trainer, [[http://www.youtube.com/watch?v=xbvA8H0MoCg this]] would be his battle theme.
** [[http://www.youtube.com/watch?v=uYyzc8vffKk "You Will Know Our Slams".]]
* The track for the [[http://www.youtube.com/watch?v=4syAd9dOBZY Central Factory]] deserves mention, for the rhythmic beat and the bass! It suits the look of the area perfectly.
* [[http://www.youtube.com/watch?v=iPpxevmCXX8 "Satorl Marsh (Night)"]]. Satorl's [[http://www.youtube.com/watch?v=ZXZI_5YXceE Day Theme]] isn't too bad either.
* [[http://www.youtube.com/watch?v=OZ3j12pF84o "Unfinished Business"]]. Once again, Yoko Shimomura showing off. One of the best battle themes of the game, which you only hear once, and it doesn't even loop. Despite that, ''everyone'' remembers that track, for good reason. It is that good.
* [[http://www.youtube.com/watch?v=oGw5kwHl_LU "Mechanical Rhythm"]]. The battle theme you get for the Mechonis Arm and Mechonis itself, it appears to be made up, appropriately, of snippets from other songs, including the boss theme and Gaur Plains, all melded seamlessly together.
* [[http://youtube.com/watch?v=-r-ndNVLmDU "Irregular Bound".]]
* [[http://www.youtube.com/watch?v=-nCh8_DOdBI "Beyond the Sky"]]. Creator/YasunoriMitsuda, of ''VideoGame/ChronoTrigger'' fame, came to work on just this one song.
* [[http://www.youtube.com/watch?v=1z_aTahDPHk "An Obstacle In Our Path"]] is the most epic. Boss. Battle Theme. EVER!!
* [[http://www.youtube.com/watch?v=3XVSwe2HBIs "Everyday Life"]] is aptly named, and a fitting interlude piece for the game's lighter, softer moments.
* [[http://www.youtube.com/watch?v=1NM0VUsIHoY "Bionis' Awakening".]]
* [[http://www.youtube.com/watch?v=Bl45h7YMIQc "Zanza's World".]]
* [[http://www.youtube.com/watch?v=v6xQyJlt7EE "Zanza The Divine".]]
* [[http://www.youtube.com/watch?v=l2z2UPSQdn0 "The God-Slaying Sword",]] [[spoiler: the final boss theme.]]
* [[http://www.youtube.com/watch?v=k9rtjYuloKQ Imperial Capital Agniratha]] is beautifully somber and perfectly suits the ambiance of the once great capital, which has long since been [[spoiler: abandoned]]. The rendition that plays [[http://www.youtube.com/watch?v=c_gH2vPmr2U at night]] makes it even more so.
* [[http://www.youtube.com/watch?v=Umfc69VlAF4 "A Tragic Decision".]]
* [[http://www.youtube.com/watch?v=RmfRj1t3NRg Valak Mountain - Night]] and [[http://www.youtube.com/watch?v=9cuSqIEj7z8 Day.]]
* [[http://www.youtube.com/watch?v=_wdc_cDaUNQ "Engage the Enemy"]], the closest thing this game has to a victory theme. It plays pretty much whenever something badass is happening during a cutscene, from Shulk learning a new Monado power to the party delivering the [[CoupDeGraceCutscene coup de grace]] on the boss they were just fighting.
* [[http://www.youtube.com/watch?v=9b83Ii14AAI Both]] [[http://www.youtube.com/watch?v=_hPeaDXzDEo themes]] for Bionis' Interior, while not usually considered the best songs in the game, are appropriately unsettling. The first version, "Carcass", plays on your first visit (and you may only hear it once since you are only required to go through the interior once early on), and [[WombLevel in combination with the scenery]], reminds the player that one of the game worlds is the corpse of an organic giant and provides one of the very first hints that [[spoiler: despite being the home of some good people, [[HumanoidAbomination the Bionis itself is not really a benevolent entity]]]]. The second version, "Pulse", plays [[spoiler: once the Bionis wakes up]] and replaces "Carcass" from then on. Appropriately, it has the same melody, but is now sped up, [[spoiler: going along with the Bionis being alive again]].
* [[http://www.youtube.com/watch?v=fkq8vwBV8Zc "The End Lies Ahead"]], the last dungeon's theme [[spoiler: depicting in traditional "Xeno" fashion a band of heroes storming God's backyard, swords drawn and guns blazing,]] which manages to be both bombastic and somewhat melancholic.
* [[http://www.youtube.com/watch?v=W7z49VNt3IM The Battle Is Upon Us]], the theme for [[spoiler: the Second Battle of Sword Valley]].
* [[http://www.youtube.com/watch?v=J4uoZuGy4AY Once We Part Ways]], which notably plays [[spoiler:when Shulk becomes a god at the end of the game and changes the destiny of the universe.]]
* [[http://www.youtube.com/watch?v=AhhZ1p0eUWM Thoughts Enshrined]], a very somber track that plays for a few of either the most SugarWiki/{{Heartwarming|Moments}} or [[TearJerker tear-jerking]] moments in the game.
* [[http://www.youtube.com/watch?v=1w-TJX5KRMY Frontier Village (Day)]] and [[http://www.youtube.com/watch?v=fyKtvH5eqe4 Frontier Village (Night)]]. A pair of the most welcoming themes for the home of the Nopon.
* [[http://www.youtube.com/watch?v=1MeRnj6iZe8 Rage, Darkness of the Heart]] is able to sound both epic and tragic, fitting moments it plays in like [[spoiler: Shulk attempting to kill Metal Face after he "kills" Fiora, the death of Xord, Shulk relenting on killing Egil, and the death of the penultimate boss, Dickson.]]
* [[http://www.youtube.com/watch?v=ODJyvWBTegE A Friend On My Mind]] is easily one of the most heartwarming tracks in the game. You can almost hear the friendship the song is meant to punctuate.
* [[http://www.youtube.com/watch?v=FL9OrUZJhpw Riki The Legendary Heropon]] fits Riki's goofy personality perfectly.
