I chose The Book of Souls, Shadows of the Valley, and Empire of the Clouds. The chorus from the title track is definitely my favorite on the album: "Prophecy of sky gods, the sun and moon. Passing of old ways will come true soon. Falling of ages, forest of kings. The search for the truth, the book of souls"
From Shadows of the Valley: "Into the valley of death, fear no evil. We will go forward, no matter the cost. Into the valley of death, follow me now. Bring me your souls and I'll make it our last"
I love Empire of the Clouds! It's definitely my favorite on the album. Currently, it's my second favorite Iron Maiden song, behind Wasted Years!
