Fun Facts regarding the "Alphabet Song":

* Do you know your ABCs?  If you do (and you should), this song will be a walk
  in the park.  If not, consult your nearest preschool.

* Expert, like the Oni chart in Taiko no Tatasujin, is deceptively difficult;
  it's a kinda crazy 10-footer with some hands and lots of added fanciness.

* The other four difficulties are just a matter of knowing the song's melody.

-> Revised November 13, 2013: Re-BPMed; the BPM was wrong.  This is fixed.
