I'm trying not to form any opinions based on track lengths. I generally prefer longer songs, but that doesn't necessarily mean that shorter songs are bad or less developed. But I have seen comments along the lines of shorter means they are "trimming the fat," or the equivalent. I strongly disagree with that sentiment. That assumes there is "fat" that needs "trimming" in the first place. Even in DT's longest songs, I find very little that, to me, sounds like something that should have been trimmed down. There are only a small handful of songs that I felt contained songs that could/should have been trimmed down just a bit where that would have made them "better" songs (off the top of my head, the only ones are The Glass Prison, This Dying Soul, Endless Sacrifice, Repentance, TMOLS, ANTR, The Shattered Fortress, and TCOT).
