The song sounds like it fit into jigoku no shoujo soundtracks which makes it feel a bit like asian priest song to me. As it begins dark and gets lighter then the music fades away around then 3;30 sounds like something horrible happening everyone filled with sorrow.The the end sounds like the sun is rising over the horizon and a brand new day has come, so leave your sorrow away or something. I'm not a fan of the ending just personal taste but i suppose i would justify if the ending which starts around 3:10 was not only the ending but the beginning of another song so you use it transition from this song to another.

But nonetheless amazing thx.
