While going through my various burnt CDs I came across a gold mine of misc anime songs, one of which is a very fast dance/J-Pop song. I think it's called "Go to the light" or "Go into the light" idk. It sounds like it could be either an opening or an ending theme, and midway through the song it sounds like a victorian sort of carousel or music box. Anyone have any idea where this anime song could be from? I'll post a link as soon as I can.

I think you're referring to the Star Ocean EX opening?
