Here are my thoughts:
That Equilibrium track... UGH, it's that album where they switched from their epic melodeath/symphonic/folk metal roots to this sh*t! This one seems closer to those roots though. I say it's symphonic power metal with the death growls happening as frequently as some of Epica's greatest hits, so it has some Guardians potential.
Passcode sounds closer to trancecore in the same vein as Fear and Loathing in Las Vegas, though with a Babymetal-inspired Japanese girl lineup. This can definitely stay in The Revolution, but under the trancecore banner.
DOLL$BOXX, yet another Japanese female band with the trance metal label. In my opinion, this sounds like the synth-powered alt-power metal sound that Machine Supremacy has, though not as 8-bitty, and with more emphasis on the "alt-" and a bit of screaming. The Gateway it is for this track, then.
So, if we include the tracks from the previous round, including the bonus Amaranthe track I suggested, my voting points are: The Guardians - 4, The Revolution - 2, The Gateway - 1. It is most likely for trance metal to be suited nicely in The Guardians as a power metal genre, despite slight potential in The Revolution. Let's see what the rest thinks first.
