Very tough choices again.
Purgatory and Lord of the Flies are two of my favourite songs. Although it was very difficult to choose, I voted for Purgatory, because it means more to me purely emotionally. I chose 2 Minutes over The Prisoner for the same reason, though I see them both on equal terms musically.
Sign of the Cross and The Evil that Men Do is another tricky one - they both have some of my favourite guitar melodies. I went for the latter, mainly because it's so catchy and makes me want to listen to it over and over again.
Finally, Paschendale v Infinite Dreams - very different songs, but both very powerful. I opted for the former because it was one of the songs that moved me the most when I heard it for the first time, almost to tears. Infinite Dreams is a masterpiece, though.
Elsewhere - Deja Vu, Wrathchild, No Prayer (it's in my top 10), Still Life (top 10 as well) and Brave New World.
