I really do play with huge armed forces in my normal games. This mod however is very taxing since the models are more intricate. There are sure mods where I can play with Do my Assignment more than 1000 troops on screen at once and unlimited corpses in real time. With respect to the music, it's the "Necropolis Theme" from one of my most loved recreations growing up "Saints Of Might & Magic 3". Brings back incredible recollections.
