I like IT. Furthermore, I think it's the best song of DT12. However, it's overly long for the real content it has. The outro, could easily be another song called "Jordan Rudess Outro for Concert endings". The ambiance part is another waste of time, it reprises Tuscany's idea, the orchestra is a nice touch but yet again I'm feel trapped in the idea of Six Degrees of Classical Music.
Unfortunately, in addition, due to the fact Mangini drum mix come from the 80's I believe that without a decent live version of IT, I'll lose my interest of coming back in the long run.
Octavarium, ACOS and TCOT are probably better.
