Magical
I love this soundtrack, it's very magical and fantastical in a very French way. I think especially the Valse comes off very parisien of the romantic era where they seem to be perma-stuck in the '50s. It's very jolly, tombe d'amour kinda stuff.

Absolutely wonderful
I popped on my Amelie DVD a few weeks back and as I was being wowed by it again was noticing how nice the music was. I decided to explore the music further.

I've been listening to this soundtrack for several weeks straight now, several times a day some days. When I'm not listening to it, I'm humming it or hearing it in my head. I absolutely love this score and would recommend it to anyone who likes soundtracks or instrumentals.

This is a work of startling originality - there is such a variety of instruments and themes that only a handful of songs sound alike (most scores have a central theme that runs through virtually every song). Despite all the titles being in French, a language I don't speak, the tracks are so identifiable I know many of them by name. You can't help being picked up by the spirit of the music as it twists and turns playfully, almost organically.

Simply - beautiful.

simply delightful
This soundtrack is probably one of the most enjoyable to listen to as an album, as opposed to "the movie had great music but compiled on a disc it just doesn't have the same magic." The music is definitely one of the major components of the movie, and the album is not disappointing.

Magic
Magical. Fantastic. Amazing. There are many other words I could list, but you don't want to hear them all.
This album will not disappoint you, the music is awe-inspiring. La Noyée and La Valse d'Amélie are simply the most fantastic songs I have ever heard, as are the rest.

In No Particular Order...
Thoughts on the album, in no particular order:

First, it's the ideal musical counterpoint to what the film is visually. Similar to the movie's simple-but-saturated visuals, and the quirky bits of mise en scene contributed by artist/illustrator Michael Sowa (whose work is also worth checking out in its own right), Tiersen's score wrings an awful lot of meaning from whatever's at hand, from toy piano to typewriter, and all points in between.

Second, if you're a fan of what I'll call "semi-serious" music--stuff that's somewhat, but not quite, classical, and that doesn't take itself all that seriously--you'd probably find this enjoyable. Yes, it sounds like Satie in some places, Nyman in others. If you're a fan of Penguin Cafe Orchestra, as I am, this is quite nearly a Francophile version of that. Or, if you'd prefer, some of the more cinematic offerings from Pat Metheny (think of the sunnier bits from "Secret Story").

Finally, though, the best comparison I can think to make is to an album this sounds nothing like at all: Peter Gabriel's "Passion" (the soundtrack to "The Last Temptation of Christ"). Reason being, this is one of those rare soundtracks that, while it vividly evokes the film for which it was written, stands very well on its own. If you've seen the movie, it will bring you right back to that; but if you haven't, put it in the player anyway... you'll find that your imagination will supply plenty of visuals to go with the music.

Added note: One bit of incidental music appearing in the film (and which was also used in the trailer and commercials, if I'm remembering correctly) that doesn't appear on the soundtrack is titled "Quimper 94," and can be found on "La Valse des Monstres," which is also worth a listen.
