Generally, I like that song for the most part of it, but...
The tonality of that particular song may not appeal to me in whole...
It's hard to explain it. It hasn't got to do anything with heaviness of the riffs or its rhythm pace. The chorus is based on that frigid/diminished scale that makes it more extroverted, so doesn't quite move me. I guess I'm a more melancholic, sad type of a person. For example Eyes Of Medusa, while being ultra heavy rhythm guitar-wise, it's verse is one so sad it almost brought me to tears. Same could be said for King Of Terrors, Awakenings, middle parts of DWOT etc. It's just that dark, sad dramatical tonality that Symphony X usually posseses, song Pharaoh may lack a bit.
