Coming from someone who loves metal mostly because of the music, that sounded pretty good. The first one was better imo (the second one had parts that sounded more like dubstep than techno). And a verse or two with clean vocals would be nice xD Not that I mind the screaming, just think it would sound better with some clean vocals.
Two songs that I really look to for support. Really good morals and message... If you need to, Read the lyrics.
