A fuzzy "dark" feeling inside
I have to admit, I thought you were just trying to bribe Tom when you told him to review this, but I can see that there may have been more to his reasoning. Anyways...
It really has a nice evil feel to it. I really like the part after the beginning. In a way, it reminds me of an urban rogue (Sam Fischer maybe? feeling more like Thief in modern days honestly) buzzing around a building, taking people and/or guards down with stealth kills. At around 2:45, the feel gets a bit more chaotic, but the throwing in of words at that point kind of ruins the daydream. It still has the feeling from earlier on, so I just played along with it until I heard the opening music again. That was the main annoyace however. All in all though, this is a fine song. I will say this much as a leaving comment.
...It's going onto World of Warcraft with me (addon lets me listen to music like this while I play it)
