I don't worry about categorizing into genres. That's a job for librarians. :P
The logical word to replace "hell" would be "ill," in the context. But it wouldn't have quite the same level of meaning. Also, it just technically sounds better sung with an H in front.
I love the atmosphere this song evokes. It's very well suited to this year's BIONICLE story arc. Alas, however, the theme of the song resonates less with me than does "Creeping in My Soul," "Gravity Hurts," or "Closer to the Truth." I'm sure it'll grow on me as I listen and digest it more, though.
I fixed a couple of words for you guys:
Release...
Let me take on eternity
Taking one more step
And let it rip through me.
I'm building up my nerve
So you can wish me well
Or you can wish me hell.
From pride we'll fall!
Bye bye Babylon!
Once reaching for the sun,
Depraving everyone.
So don't you know,
You don't belong.
Bye Bye Babylon!
Now scattered, you were wrong
Left burning in the sun
We'd better be...
Bye Bye Babylon, begone!
Unseen...
The crime of destruction is facing me
I wanted to retreat,
But you won't let me be.
I'm calling for belief.
Be sure, I will be there.
And you will fall! [fade]
Bye Bye Babylon!
Now scattered, you were wrong.
Left burning in the sun
We'd better be...
Bye Bye Babylon, begone!
Bye Bye Babylon, begone!
Bye Bye Babylon, begone!
