The Book of Souls is easily 'top 5 ever' material for me (possibly top 3 post-reunion). But it seems I can't put it over The Legacy. For years this one has been simply engraved in my brain as the ultimate masterpiece. It's funny that so many songs are longer than The Legacy but none is more massive or epic. It always feels longer than it is, but in a positive sense of course. Dance of Death is a classic very close to the two I mentioned, but e.g. The Talisman is nowhere near that level (although it's a brilliant track). Plus, I've always thought Lord of the Flies is underappreciated. Excellent rocker, should be played live more often.
