I've had this song:

YouTube - Dryad A Green Memory

For about a year now, and from the first time I heard the intro I could have sworn it was sampling a song from a Final Fantasy, or at least an RPG, but despite searching through a few soundtracks I haven't been able to find anything similar. I've linked it to a few people I know from here and we all seem to think it sounds like something from FFX, but no one knows what. So I put it to you, general public, to see if we're right or if we're all nuts.
