* ''Xenosaga Episode III''[='=]s soundtrack by YukiKajiura is nothing short of amazing, as is the venerable YasunoriMitsuda's efforts on I.
** Special mention must be given to [[http://www.youtube.com/watch?v=eUcxlxhlRvo godsibb]], which is widely regarded to be one of the best songs in the series. Its [[http://www.youtube.com/watch?v=JrBk3oZ2jc0 live performance]] is a CrowningMomentOfAwesome on its own.
* Hell, even II, whose soundtrack is fairly mediocre overall, still has some of the best songs in the series. [[http://www.youtube.com/watch?v=eTujeWkIhtE Communication Breakdown]], [[http://www.youtube.com/watch?v=UgG5SEHTKgU Fatal Fight]], ''Here She Comes'', ''Battle Of The Elsa'', ''Chase'', ''Sakura'', ''Sweet Song'' ... real diamonds in the rough, no question.
** To be specific, all of the tracks composed by YukiKajiura are spectacular. Too bad that the rest are (arguably) among Shinji Hosoe's worst works ever.

* The [[http://www.youtube.com/watch?v=CzJ15BSSI9M ''Sakura'' theme]] in ''Episode II'' and [[http://www.youtube.com/watch?v=dIReESnbO0c ''Hepatica'' theme]] in ''Episode III'' (arguably the themes for their respective games) are truly awesome. Not in the way to inspire awe and terror, but the way they draw out TenderTears in how ''beautiful'' they are. The song ''Testament'' from ''Episode III'' can produce similar feelings... Well, at least [[http://www.youtube.com/watch?v=hAF3k7ak55U the beginning part of it.]]
* ''Xenosaga I''[='=]s [[http://www.youtube.com/watch?v=9_NKJNo7nx8 battle theme]]. Pure orchestral awesome.
