I didn't remove this for it, since it still technically inserts fine, but the song outputs a bunch of unexpected character errors because of this section:
[o3 Kick g 16r16 Kick g 16r16 Snare d 16 r4 r16 Kick g 16r16 Snare d 16r8.
Kick g 16r16 Kick g 16r16 Snare d 16r16 Snare d 16r8. Kick g 16r16 Snare d 16r16 Snare d 16r16]24
Your note lengths are almost all separated from the note definitions for no visible reason; luckily you have an l16 command earlier in the song so it still recognizes the notes as 16ths, but please keep this in mind in the future (to people using the song: just ignore the errors).
