Honestly, if Phantasy Star Online 2 isn't famous for its plethora of Fanservice Costumes, it's famous for this. Every square inch and meter of this game's soundtrack is filled to the brim with fantastic music, and, well, let's just say we'd be here all day if we were to talk about all of them.
- The "ARKS Ship Inferno" Emergency Quest plays the theme song of Burning Rangers to get you in the mood to put out fires and save lives.
- Seabed's theme, both the tense yet beautiful Battle variant and the soothing Calm variant.
- For being such an underused gameplay mode, Challenge Quests have an absolutely spectacular sound lineup.
- The field music for Tokyo has a feeling of mystery and surrealism, perfect as you duel the Phantoms in the streets.
- The Riding Quest themes, "Neon Days" and "Neon Nights", performed by Runblebee, which just rocks.
- The theme for Mother Cluster's moonbase, in a rather cunning move, is built with elements of various sections of Beethoven's Moonlight Sonata. Using the linked video as reference...
- Big Vardha may have been one of the first bosses, but its theme takes the cake through sheer awesomeness. And it just gets better from there.
- The theme of Dragon EX features Orchestral Bombing at its finest.
- Many consider the theme that plays during Dark Falz Elder's preliminary fight against the Falz Arms to be extremely epic.
- Then comes in the proper battle theme for Dark Falz Elder, titled IDOLA the Sledge of Destruction. Over-the-top title much? The song itself far surpasses its epic name, which is saying a lot.
- Dark Vibrace's theme. The perfect theme for the final wave of the Tower Defense Emergency Quest.
- The theme when you showdown with Deuman Theodore is pretty darn good.
- Dark Falz Loser, the deadliest and most challenging boss in the game to date, also brings with him one of the greatest boss battle themes known to recent history, with its haunting Ominous Latin Chanting, powerful instrumentals that respond to Loser's phase changes (and even a Musical Nod to Olga Flow!), an incredibly tense mix denoting the incoming One-Hit Kill, and to top it all off, a new mix of "A whole new world" with 100% more Ominous Latin Chanting to remind you that what you've started isn't over yet.
- The theme of Falz Dourumble, "Chaotic Dynasty", is just as imposing and frenetic as its title suggests, yet also has a sort of playful bounce to it befitting Double's twisted mindset.
- "IDOLA" the Audacious JOKER", Dark Falz Double's theme, is tense and fitting for the most utterly deranged boss in the game. The music in the first phase is a mixture of awesome and dread-inducing. When Double loses around 50% of its health, the music suddenly goes ballistic for a moment as Double turns into a cluster of rockets and tries to run you over. After that, the original music continues in sped-up and higher-pitched version while Double throws everything it can at you to keep you from reaching the Profound Darkness.
- The Profound Darkness' battle has three examples in a single boss battle!
- The first phase has an absolutely amazing remix of Ooze, the original Profound Darkness' theme from Phantasy Star IV.
- Instead of incorporating elements of the song into its boss theme, its next phase has a flat-out remix of IDOLA The Strange Fruits. And it is also amazing.
- And then when the fight is nearing its end, another new mix of "A whole new world"! This time with 100% more electric guitar!
- Whatever track plays during the Bad End fight with Matoi Viel, carrying home just how tragic the entire situation is with a single, sad piano as you fight.
- "Borderless" basically takes the awesomeness of Tokyo's BGM and cranks it way up so it suits fighting a laser-armed, missile-raining World War II battleship with a small squadron of mecha.
- ESC-A Falz Mother brings with her yet another spectacular remix, this time of "Death Place" from Phantasy Star II.
- Episode 5 gives us Dark Falz Persona. First two phases start off with two of four remixes of the previous Omega Falzes. Then he puts on the Persona mask and we get "Over the Universe" and the real fight begins.
- The bosses of both Sector 3 quests of Fleet Interception are accompanied by "Battle Stars", the lyrics pushing the players to fight for their future.
- "Resonant Defensive", the extended version of "Resonant Nation" from Mining Base Defense: Despair. There's even MORE beyond Dark Vibrace's theme and the build up is intensely well done.
- "Resonant Catastrophe", the theme to Mining Base Defense: Demise, starts off familiar enough... then the new OST hits partway through Wave 1, which brings the awesome from Despair and cranks it up to TWELVE. Wave 4 in particular is regarded as absolutely godly.
- The one and only Takenobu Mitsuyoshi brings his star power to PSO2 with "We're ARKS", and it is glorious.
- The PSO2 Live Broadcast crew proves that Quna isn't the only one who can rock the ARKS stage with their own infectiously catchy hit, "Rare Drop KOI Koi!".
- Xion's theme has a very ethereal feel to it, accompanied by a soothing violin that gives it an air of mystery.
- Luther's theme. Elegant, mysterious and sinister.
- Mother's theme is an eerie yet calm electronic tune. It's also a remix of the original Xion's theme.
- The Screen-to-Stage Adaptation is no slouch in the music department: just have a listen to "Phantasista"!
- Although reception to the anime has been rather cold, "Rare Drop KOI Koi! One More!" has been very well received by those who bothered to tune in.
