Ayu's interludes, intros, and outros discussion: what do they mean?

[EndOfTheWorld]

I guess I start at the very beginning for now.
I admit I don't have much to say about Prologue honestly. I feel that it mostly was added to give the album a luxe feel. To set the tone of the album too. I have always enjoyed it and would be sad if it was never included originally. The Hybrid Remix is awesome too, I listen to that version the most. If the acoustic orchestra version was used on the album instead I think it would have added more to the album and been more memorable. But the original has a slight wintery sound which is a light theme throughout the entire album so it connects. On top of the things you mentioned, I also associate the A Song For xx album with a sad and lonely Christmas. But on a lighter note, doesn't Prologue sound like it could be the music the plays on the start screen of a Playstation 1 jrpg?
