DESCRIPTION:
This is the Majestic 12 theme for Deus Ex, composed by Alexander Brandon, and as such, I do not own any of this. It belongs to Ion Storm and Eidos Interactive.

00:00 to 01:40 is the non-fighting, standard music that plays when you're not doing anything special.

01:40 to 02:50 is the fight music. It plays when you've recently engaged enemies or when you've been discovered by the enemy.

02:50 to 05:34 is as far as I know the music that plays when you talk to someone, usually Miguel, one of the few friendly people in the Majestic 12 section. I might be wrong though, but I hope this is correct.
