Since I've been a fan, I've seen ToT ass-raped and then inducted into an album people pretty much all like.
Octavarium, same thing basically. Especially in terms of the title track. At first it was just OK, and now it was DTF's favorite song last year.
Systematic Chaos hasn't been out long enough to really tell, but I think it's pretty obvious that people have started warming up to it.
People went crazy over Black Clouds at first, but it's stale. I'm curious to see where it'll end up in people's rankings a few years from now.
And of course look how people have flipped on Falling Into Infinity. We might as well put it up there with Awake and Images.
