I didn't give this much thought, but I'm sure it would look something like this:
1) These Walls
2) Hell's Kitchen
3) The Great Debate
4) Octavarium
5) Disappear
6) Blind Faith
7) Six Degrees
8) Sacrificed Sons
9) In The Name of God
10) Trial of Tears
Close calls: Learning To Live, Bridges in the Sky, On The Backs of Angels, Hollow Years, Beyond this Life, Finally Free (I struggle to rank SFAM songs separately).
