WDADU: My favourites are pretty evenly spaced. Fortune, Ytse, Fuse and Time. Probably A Fortune in Lies into Status Seeker. Status Seeker is the most fun of all the lower-tier songs, and Fortune is possibly my favourite of the upper-tier.
IAW: Take the Time into Surrounded, narrowly pipping Wait for Sleep into Learning to Live.
AWAKE: 6:00 into Caught in a Web. Short, chunky, fun songs are what Awake does best, and these are two of my favourites in the whole catalogue, in a tier with Erotomania.
FII: Peruvian Skies into Hollow Years. Much as I love Hell's Kitchen, Lines in the Sand - while cool - is not particularly one of my favourites. Peruvian Skies and Hollow Years are my two favourite songs on the album, and they're right next to one another. Their respective extended live versions would gain yet more "cool points."
SCENES: The Spirit Carries On into Finally Free. Although I did originally put Fatal Tragedy into Beyond This Life, my third-favourite into my second-favourite beats my first-favourite into my fourth-favourite. TSCO into FF just keeps on getting better, and while I like FT more than any other song off SFAM, and I do love BTL, it's a sheer drop between them.
SDOIT: Blind Faith into Misunderstood. Probably sacrilege not to put TGP, but I find Misunderstood a lot more fascinating. TGP's thoroughly intense and heavy and that's wonderful, but Misunderstood starts off with a lot more heart, then it gets downright creepy. Love it. Brilliant bit of music.
TRAIN: Stream of Consciousness into In the Name of God. Train of Thought is one of those albums where each successive track is better than the previous, more or less. SOC and ITNOG are both top five tracks for me, so they don't get much better than this.
OCTAVARIUM: Sacrificed Sons into Octavarium, although there's not a weak track among 'em. Recently listened to this on a journey and remembered why I loved it so much. There's not a single moment I'd change.
SYSTEMATIC: Any of the first half would be eligible, but I'm gonna plump for In the Presence of Enemies pt. 1 into Forsaken. I'm more likely to put on Constant Motion into The Dark Eternal Night, but ITPOE/Forsaken is better.
BCSL: The Best of Times into The Count of Tuscany. Back in the day, it would've probably been A Rite of Passage into Wither or Nightmare into Rite, but I've recently finally got into TBOT. Fantastic bit of music, though TCOT is far and away the standout song on the album.
