Ooh boy! Semi-Final time!
As much as I absolutely love A Change of Seasons, Breaking All Illusions in the Final would be an absolute fairytale for a Mangini-era song, so I'm voting for that. If it loses here, though, it's still a fantastic achievement for the song, and sets it on its way to becoming one of the Immortal Classics.
The 2nd matchup was a bit more difficult, but I went for Octavarium, the song that got me into Dream Theater in the first place.
Shall be donning my best bib and tucker for the Grand Final in a few days!
