In response to music fan from Florida, open your mind a little!
Judging from your rather ignorant review, you
a) know absolutely nothing about electronic music and are in no position to be talking about its use in the film, or anywhere for that matter
(hiphop beats? are you serious? this is the farthest thing from it!),
b) are unwilling to accept things simply as they are, and
c) have no appreciation for the way in which this soundtrack works its way into the film and under your skin, giving it so much more depth.
Yeah it's sparse, but so is Sy's whole existence, and in that respect it is a perfect match. Would you have liked to have some overt, bombastic John Williams orchestral accompaniment? I know I wouldn't. Seeing as how most of it is strings and what not, this is nothing "like the type you'd hear at some rave or trance dance gathering." Trust me. I know. Xenophobia/philia has nothing to do with it. Since most to all music out there is electronic in the sense that it is almost always manipulated post-production, there really is no grounds to be so irate. Never mind about production processes, what really matters is the emotional impact of the music and its seemless integration into the film.
One minor problem I did have was that in a couple of spots, the music brought me back to Der Krieger und die Kaiserin, also a Klimek/Heil score, but that's only from my own experience, and actually its a compliment to their resounding style.
"Throbbing techno hip-hop beats." I laugh.
