Fun Facts regarding "Koi wo Shiyouyo":

* This is the first Chata song that made it into my main pack
  (there was previously a single, "Sabishinbou").

* This simfile has tons of rolls because of Chata's well-known
  love of xylophones.

* Due to the way xylophone rhythms are, this song marks the
  first time I've used 64th notes at regular speed, for those
  fun notes in the chorus.

* This simfile is also full of tempo stop gimmickry during the
  chorus.  They go along with the background melody, not the
  lyrics (so it's a tad confusing at first).

* This simfile was charted with one express thought in mind:
  fun.  If you don't have fun playing this, I've failed.

* Hard is meant to be the most fun, leaving only minimal
  notes out during the chorus.  There're some 64ths in the
  chorus on this difficulty, but they're easier to hit than
  on Expert.  The slowdown section is also a lot of fun on
  Hard.

* Expert leaves nothing out; you even play the background
  melody rather than the lyrics during the slowdown section
  (which is full of fanciness).

* Medium is a kinda difficult 7, but it's not so bad that
  you'd fail easily.

* Easy and Novice are pretty fun too for their difficulties.
