I usually have a top 3 for every album. Currently it looks like this:
1 - Answering the Call
2 - The Alien
3 - A View
It's funny how Answering the Call is like a song I always expected to hear from them without even knowing!! Killer song.
And The Alien is just amazing to me, it is a perfect "mini-epic", it was the single and still what a great tune.
For the third one, it varies for me from time to time between Sleeping Giant, Awaken the Master and the Epic, such awesome songs.
