Love the fact that it reprises the theme from the Messenger but with in a more mature, ambitious way. Also, really like the David Wise-inspired touches at the end (or at least, so they sound to me)
The new section of the song is equally amazing. I'm lovin' it! Eric W. Brown from Rainbowdragoneyes is without doubt my favorite American video game composer. He's a GOD at writing catchy melodies and basslines.
