History YMMV / CosMO

* MemeticMutation:
** Top 10 rappers Music/{{Eminem}} was too afraid to diss. [[labelnote:explaination]] Miku's very fast singing in "Disappearance" and "Intense Voice" is often jokingly compared to Eminem. [[/labelnote]]

* WheelchairWoobie: Adventurous Girl doesn't have a wheelchair, but she's unable to walk in her normal form.

** In ''VideoGame/HatsuneMikuProjectDiva'', ''Intense Voice'' is universally recognized as '''the''' hardest song in the franchise, bar none. Its re-release in ''F 2nd'' doesn't even remotely compare to the burning hell that was the original.

* WhatDoYouMeanItWasntMadeOnDrugs: A good chunk of his earliest works (and some of his modern ones) were ''very'' bizarre, to say the least. The ''Rampage'' series, "Magical Girl Radical Paint" and the Magical Kitty Len Len duology are the biggest examples.

** He returns to his title as this in ''VideoGame/ProjectSekai'', with his two most notable songs ("Disappearance of Hatsune Miku" and "Intense Voice of Hatsune Miku") being at the top of the difficulty chart at level 28-29. Then he managed to dethrone ''those'' with his commissioned song for the game, "Machinegun Poem Doll", bringing the difficulty cap to ''34''. And since [=cosMo=] can't seem to get enough, his entry to Proseka ULTIMATE, "Yaminabe!!!", joins the ranks thanks to it's new mechanic of adjusting note speed to the song's BPM rate on harder difficulties.

* NightmareFuel: "HYPER∞[=LATiON=]" and "Demise of Hatsune Miku". "Sadistic Music Factory" is also rife with this, being about Miku forcing her producers to create music without stopping for her forever.

** "The Intense Voice of Hatsune Miku", in great contrast to "Disappearance", shows Miku being able to come to terms with her fate of eventually being forgotten and deciding that as long as one person finds joy in hearing her voice, her existence will never truly fade. It's emphasized further by "Hatsune Creation Myth", written 10 years later, where the sheer amount of people helped by Vocaloids has ensured that her existence will be remembered for years to come.
