Yeah that part
. I compared to flagcarrier, it's as closest as can be, but ain't 100% the same (IMO)
Oh saw that quote, it's not logical though cos all the other samples are from MaSu songs, right?
Okay, firstly (if you dont know)... Robert is the vocalist (and one of the guitars might I add) of Machinae. You can take what he says as fact. For example, if he tells you I rock, it's because it's true.
Second, Dark City IS a Machinae song. It's planned to be on the third album. Nope, theres no where to download and nope no one (save for MAYBE personal friends of the band) has heard it. But it is an intended track for the third album, so they are all in fact Machinae songs. The other "cuts" from Machinae songs are all released songs as you know, that one is the exception. I think of it as a taste of things to come. We'll hear it eventually

But anywho, long story short Dark City is a Machinae song and it should be on the next album.
