This is a great vocaloid tune, one of my favorites.

The mp3 is attached.

I already made a stab at it, but I was too lazy to try and do a transcription of the full arrangement. Usually I just do the melody and chord progression.

Anyone wanna continue? I only did the first 8 bars lol, but it took too long...

I also attached the MIDI of what I did so far (via lilypond).
