Lol.. I checked out that song. I was like... well, the definition of metalcore sure has changed if this is metalcore. Then right in the middle "ARID JFLJTL KJADAF!" Oops, never mind

But ya the lyrics are nice... if you read along.
I don't know if you'll like any of these cause none of these bands are anything like that but, anyway, never hurts to check them out I guess...
Theocracy
Barren Cross (80's Iron Maiden type stuff)
Rob Rock
Mehida
Harmony
Darkwater
Wingdom
Stryper
Seventh Avenue
Magestic Vanguard
That's all I can think of right now. Top 3 are my favorites though. Excellent solid bands. The rest are good and have some really good strong songs but then they have a bunch of crap too.
