After a considerable amount of thought, I believe the appealing thing about the music I heard was its resemblance to the light but complex jazzy stuff I remember hearing in a couple really nice department stores my mother used to frequent when I was really little.
Which is probably not what they intend.
Anyway, I got my copy of The Two Towers: The Complete Score. Again, it is too awesome for words. There's a spifftacular book included and the single disc with three hours of DVD-Audio is worth the $60 bucks I spent, easy.
I'm listening to the The Fellowship of the Ring - The Complete Recordings in Dolby Digital 5.1 (AC3) and they sound great even in stereo.
Is there a specific audio player I should be using for this? Windows media player actually works, but doesn't seem to like the ac3 extension association. In any case, I like it.
