The important part...
"SOUND: In a first for 20th Century Fox, "Titan A.E" offers both a Dolby Digital 5.1 soundtrack and a DTS 5.1 edition of the movie. Although I'll talk more about that later, first let me say that this is really one of the most impressive soundtracks I've had the pleasure of listening to lately. Although the constant, forced legion of pop/rock songs doesn't particularly go with the movie, they sound particularly good here - loud and particularly crisp.
In fact, "loud" would be a good word to illustrate the entire soundtrack, which is often extremely agressive. Bluth's previous movie, "Anastasia", also put sound to fantastic use. With the kind of material here to go from, the sound designers have left no stone unturned, with every spaceship sound, electronic effect and explosion enveloping the viewer. Ships scream through the listening space, often making me duck out of reflex. Surrounds are put to hugely active use during the action sequences, which really do a fine job of putting the viewer even further into the experiences of the events of the movie.
Bass is definitely powerful at times, and there are quite a few scenes during the film that are "demo-worthy". The DTS soundtrack offers a minimal amount of additional clarity and fullness, but both soundtracks are for the most part very similar and quite excellent."
