I'm glad and positively surprised that the vast majority said that they like the song, I figured from reading comments here and there that it was much more disliked!
I went and relistened to it yesterday, it's such a somber and melanchonic ballad. The beginning is grandiose, and works well in compilations (for example try to play As I Am and have the ending of the song going directly into this), James sings very well the verses and we have a little nice touch from JP doing backing vocals (We know Jordan can sing as well, I doubt it but I'd love for the new album if there's a mini Jordan backup vocal spot just like JP does in this song), and then the chorus is so haunting and mesmerizing.
The post chorus is the climax of the song in a sense - it continues from the buildup of the chorus, and then reaches that beautiful "Do you remember me this time, even in death I gave you life" part... chilling! then of course comes the (in?)famous long solo section, the reprise at the end is nice because of that little moment of only piano and vocals before kicking back in with the final chorus and then going into the long and melodic solo.
Brilliant, brilliant stuff, and it's a nice contrast to all the heavier, "in your face" moments of Systematic Chaos such as Constant Motion and The Dark Eternal Night.
