What a delightfully weird poll.
I thought I was going to vote Enigma Machine, but then I noticed The Dark Eternal Night, which absolutely trashes the others. Through My Words is the only track I don't particularly care about - and even that's got more votes than the poor Shattered Fortress!
1. The Dark Eternal Night
2. Enigma Machine
3. This Is the Life
4. I Walk Beside You
5. Honor Thy Father
6. The Shattered Fortress
7. The Great Debate
8. Through My Words
There we go, I'd probably go with that. Enigma Machine is almost certainly being helped ever so slightly by the new car smell, but I do think it is an absolutely cracking tune. Crushing riffs, very technical but quite singable - This is the Life and I Walk Beside You feel like good company. Honor Thy Father and The Shattered Fortress are both direly underrated (although neither are essential!), and The Great Debate is very good but doesn't quite justify its runtime as the other songs do.
The Shattered Fortress probably has a modicum of new car smell, too. Seeing it live renewed my interest in it quite a lot - gave it a new lease of life.
