By "dissecting" music, I would call it listen and think about every little section, how it sounds, where does it lead to, what can be created next to it, do I have to repeat it or not, how many times do I have to repeat it, etc., the musician creates its ART. I tell you because I have done so when I create my own music, but it's not just me, in fact that's the way a composer works, even the greatest composers like Beethoven, Bach, and why not, Michael Romeo, that's why I found this song non-polished for the high level of passion and "detail attention" from Symphony X that we are used to.
I know it may sound a bit "technical" or "cold" but I can tell you, it's not like that.
