For me, this song is probably right up there with Liberi Fatali and One Winged Angel. It has that epic sound to it, and it was perfect for the End cutscene. It's in English, and usually that kind of puts me off songs when it comes to epicness, but this one managed to break through that stigma I put on such things. It just encapsulated everything about the ending days, and I listen to it regularly now.
What do you think of the song? Does it match the best of the best of Final Fantasy music for you?
