Yeah, basically there are two clues that aren't clear.. One is that the song is "a monster track".. IIRC Bosk never clarified what this means... i.e., if it means necessarily "epic": at least *I* took it that way, because of his reaction when ppl was mentioning songs that spoke about monsters or was "monstrous" somehow" and he said "now you're being silly" or something like that.. Because I take monster-track as epic-track (also because of the MM's tweet, although Bosk could have easily used that to mislead us), I discard a lot of songs that fit the other criteria (Panic Attack, Caught in a Web, Peruvian Skies, TSCO, etc)..
And the other is the Epica thing.. Again, if this hint is what all are saying it is (last 25 minute of albums at the end of the alphabet), then that leaves no songs at all if we consider the "played live with Mangini" and the "epic track" conditions... Well, actually, there is one, but we'd have to think that he doesn't have TOT, TA, SC, SDOIT and 8V on his work computer.. Song would be Finally Free (or TSCO, OLT or TDoE if we don't think the song is an epic and it could be an instrumental)..
PS: note that earlier on in this very thread Bosk said that he thought ANtR was played live with Mangini.... so he could easily be thinking that they played let's say ItNoG or Sacrificed Sons with MM and then any of these could be the song..
Still sticking with my The Great Debate prediction although it's very unlikely.
That song is discarded if not for the "alphabetical order" thing, then for the crowd pleaser condition..
Yeah, except it comes in 25 minutes before the end of the Score DVD Disc 2, which, for all we know, bosk could have ripped the audio of.
I don't know about that, but even in that case, Train of Thought would come after Score.. But if you're right, and he doesn't have TOT on his computer, then the song is definitely TGD... because, after all, the "crowd pleaser" condition is the more subjective I suppose..
