You just have to listen this song in full quality, meaning 28MB, 12 minutes of audio duration and some audio enhancers (I'm using them). Put some headphones, close your eyes and this song will take you in another world, I guarantee you !!! ;)
I would agree but I think you have to listen from 0.00 to appreciate the rest a la typical progressive trance, however I take your 6:25 and raise you 0:43, 3:10 (for 2 mins), and 7:10 - as you can tell I adore this track, one of the best ever underrated tracks for me
