After rehearing both songs many times over, they sound different enough. Allthough one of the tracks, then one that can be heard all the way from the beginning is exactly the same as in Not Tomorrow, only with increased tempo. Both have a similar depressing mood, but I see they're not the same, although quite strong influence can be heard.
Also whether the instruments and volume are different proves nothing, as you can change them as you please. Not to mention that the instruments will always sound different when you go from mp3 to midi, plus there's a million different versions of Not Tomorrow so there's always going to be one with different instruments. One can change all of them to banjo or whatever.
All in all, I still consider WayTraziun to be just a remix of Not Tomorrow, and as such has the originality of a remix, whatever that is.
I still want to know where Tower is from though.
