The ONLY wrong thing about the music in the Halo games is that they are way too short! The best music moments in both Halo: CE and 2 where the music gives a great feel to it only lasts around 1 - 2 minutes...
Alright, too long also takes away the feeling but I have to say that they could make the music going a little longer.
