Fun Facts regarding "Aijou Education":

* This song is sung by Little Non.  I normally don't mention
  the artist here, as it's in the info you see on the song
  select screen, but the reason I say so is that Little Non
  is probably most famous for singing the ending theme for
  the controversial anime "Kodomo no Jikan" ("Hanamaru
  Sensation," which I've not charted).  Little Non sings
  plenty of other songs that are similar in nature to this
  one, however, so if you like their style, look them up.

* This was originally written during the period when I was
  heavily Osu-style-shackled in my stepcharts.  This simfile
  used to contain one of the most obvious and annoying
  offending examples of this: the speedup section.  That was
  just a terrible, awful idea.

* Thus, as of the Ace Of Hearts Revolution (November 2013),
  that speedups have been removed, and the song now runs at
  a constant 180.
