Love this song, maybe my 3rd fav after the t/t and Sleeping Giant. One of my favourite parts is near the start, you have Petrucci's heavy, distorted 8 string riff with Rudess playing clean piono over. Love that contrast.
Also the section "you made it to the top... just to find out, you're only halfway there. All the time, missing the point of the journey." Great, poignant lyrics there (a link to the title track?) and the bass underneath is awesome.
