## unknown_midi_data.txt
If anyone can figure out what this data is, that would be greeeaaaat.  Bytes represented in hex.

Found inside a MIDI file between tracks.  Surely it's related to music somehow, like a sample..?  Not sure.
I've inserted newlines after 99 and 89, which seem to be very common bytes.

                Short explanation on why JavaScript's object model sucks
              
          
    How do you convert an object to a string?
It started out simple enough:
var s = obj.toString();

Ooops.  But wait.  What if an object has a toString key inside of it?
