I honestly love the whole piece from beginning to end. The fact it's composed as a classical piece with four movements really meshes well with the games steampunk/opera aesthetic.

With that said, I feel the third movement is my favorite because it's the one that every arrangement and remix gets wrong. Why? Because the original 16-bit version gives it this really cool echo effect, like it is really being played on an organ in a large cathedral and no one can ever seem to recreate that element for me.
