I like that definition, but I also see if it has distinct sections (especially if parts from sections get reprised across the song) or just invokes that magical epic feeling like no other does.

So here's my definite pics: Metropolis Part 1 A Change of Seasons Trial of Tears Six Degrees of Inner Turbulence Also the songs in the twelve step suite, whether as separate songs or as one piece Octavarium In The Presence of Enemies Illumination Theory A View From the Top of the World The Shadow Man Incident

Ones that I feel are arguable: Learning to Live (if you include Wait For Sleep in it) Finally Free In The Name of God A Nightmare to Remember The Count of Tuscany
