Ooh, this is a tough question. Let's see... Engage the Enemy, You Will Know Our Names, Satorl Marsh (Night), Valak Mountain (Night), Mechonis Field, Tragic Decision, Mechanical Rhythm... that's most my favourites, I think. Oh, and Fallen Arm (Night), Eryth Sea and Anger, Darkness of the Heart are incredible too, as I recall. Really, it's hard to choose because pretty much all the songs are great.
