There's a ton of things to say about this song and about this transcription (which isn't perfect, by a long shot). For instance, I'll admit right away I cheaped out bigly at the very end of the battle section. Or you could say that each part of that same battle section follows the same pattern of ABBB| ABAA| BBBB| which helps relate them to one another despite changing keys back and forth. But ultimately, I'll just say this: I will at some point in the future proofread the transcription and update this thread, but it's a really long song and you probably shouldn't hold your breath. In the meantime, please enjoy, and any feedback is greatly appreciated.
