I like it. I honestly do not really care for the whole 'and then the song transforms into the BIG MARCH OF THE AGES' as some of the folks are suggesting. There are some songs that are pretty good for a certain type of mood.
I can use this in one of my games for when I have my group explore a strange place, or when I do my own personal roleplay in that regard. I like this one a lot, since Temple of Fiends is my favoite song in FF1.
