* SugarWiki/AwesomeMusic: Most of the game's music is amazing.
** The Legendary Theme, whether played on acoustic or electric guitar, always ends up being the musical equivalent of a SugarWiki/HeartwarmingMoment.
** "Tainted Lovers", Gregorio III's song, mixes organ and shredding metal to create one of the most memorable tracks in the game.
* BreatherLevel: After the [[ThatOneBoss hellish ordeal]] that is Ben-K's shark form, Ben-K's [[HumongousMecha robot form]] and The Legendary Theme (Acoustic) are two welcome breaks before you're thrown [[NintendoHard back into the deep end]] for the rest of the game.
* DifficultySpike:
** The stages with Panpeus, Flying-O, and Mojo King Bee aren't too tough if you have a good grasp of the game mechanics. Then you hit the [[ThatOneBoss first battle with Ben-K]], and the difficulty just skyrockets from there.
** On Master Mode, you could just start the spike from Mojo King Bee. And considering that's only the [[SerialEscalation third level]]...
* EnsembleDarkhorse: Mojo King Bee is perhaps the most memorable minor boss in the game thanks to his funky, absurd scenario and incredibly catchy song.
* GoodBadBug: In the original [=PS2=] version, ejecting the disc during the fourth and sixth stages, then immediately reinserting it grants you an instant win. While there's no real need to do this in [[BreatherLevel the latter stage]], it may very well be the only way to pass [[ThatOneBoss the former stage]] for some players. Sadly, this was fixed in time for the PSP remake.
* SugarWiki/HeartwarmingMoments: Anytime U-1 starts playing the "Legendary Theme." The second time is utterly spectacular.
* SugarWiki/MomentOfAwesome: [[spoiler: The penultimate cutscene. "BECAUSE ''I'M GITAROO MAAAAAAAAN''!"]]
** Also, [[spoiler: the whole Legendary Theme sequence with Kirah]].
** Mojo King Bee's song, [[https://www.youtube.com/watch?v=ixV_Mmz2eGE Bee Jam Blues]] has been known to cause orgies when played near large crowds of people.
*** Or, hell, the ''entire game''.
* NarmCharm: By the truckload, throughout the entire game. The characters and dialogue are ridiculously over-the-top, but with all that SugarWiki/AwesomeMusic going around, it becomes genuinely good anyway.
* SuspiciouslySimilarSong: The two new songs in the PSP re-release are this, not for any specific songs, but artists' style in general.
** [[https://www.youtube.com/watch?v=UuUVHyTEuSM Metal Header]] is done in the style of Music/TheAquabats.
** [[https://www.youtube.com/watch?v=NwQNGvYUFNo Toda Pasion]] sounds a lot like the works of Music/CarlosSantana.
* ThatOneBoss:
** Gregorio and the Sanbone Trio. In Master Mode, arguably every boss/stage is an example of That One Boss.
** For those who don't see it coming, the first battle with Ben-K, which is 100% Guard Phase (read: a flurry of notes from all directions), can be a particularly insidious showstopper. If they were going for the fact that you were meant to barely escape from the battle alive, [[FridgeBrilliance Koei and iNiS did one hell of a good job]].
