As a themesong, I'd trust someone with a better knowledge of music than my vague and eclectic collection, heh.
VNV Nation's Chrome is appropriate on several different levels, though.
Foreword by the same folks is also loosely fitting, I suppose, looked at as a whole, but there's a reason I normally leave judgement on this kind of thing to others -- namely, I've a godawful ability to recall lyrics offhand unless I happen to have been listening to the group in question a fair amount recently.
Hence that both of these happen to be VNV Nation, not someone else. >_>
