Very good! HOWEVER....
There's one thing that is keeping this from being what I would consider a great movie soundtrack...
Too much PIANO.
Piano's usually don't work well in good movie score's, for something of Chrono Trigger's magnitude and theme. Think about it, we're putting this in the same fantasy realm as Star Wars and Lord of the Rings, right? Think of their soundtracks. Now tell me exactly how many pianos are used between thsoe 9 movies. I don't think a single piano is used in ALL of star wars, and there might be one or two scaterred in random songs throught the LoTR trilogy, but I'm not even sure its that much.
The ONLY song the piano would work well for in an actual movie is "To Lands Unknown". BEAUTIFUL piece, probably my favorite one. I think the piano works here because it invokes a sense of mystery.
Every other song though, the piano has to be replaced by some other instrument. They just, in general, don't work for these types of movies.
However, I COULD easily see this soundtrack being used in a videogame remake of Chrono Trigger. There's just too much piano to work for a movie though. I'm wondering if people agree with me on this.
