Engrish Gravitation style:
Never resign yourself to fate
Even if cry and anger
It's so powerful that you can't resist
Unfair but be feel top pleasure
The law of "LOVE"
- Gravitation OVA

I completely threw out proper punctuation and just followed which translations were on screen at the time.

Opening song:
Blind game again
A pretty crazed doll
Demolish the never-changing night
The light searching in the rustling breeze
Makes a noise, scattering my memory
A temptation I really should know
Don't let me down
I'm always just trying to please
Cry for the sun
I can't see anything
Who is it that cries out inside me?
Blind game again
A pretty classy doll
If it's a dream you can't reach, just toss it aside
Drastic game again
A pretty crazed doll
Demolish the never-changing right

Spicy Marmalade:
Spicy marmalade
It's as if the era is
Leading me astray with a face hiding sorrow
"What's making you tremble?"
Laugh the hedonists
A future set in place on the cool rails
Without my knowing it
The novelty gets in the way
There's something wrong with the passion
Isn't this pretty nightmarish?
My boredom is competing
Spicy marmalade
Stay used to things
And grab tonight's chance
Vanish into the night
Conspicuous marmalade
If you've found your resolve, you may as well...
Spicy marmalade
Stay yourself
And if they're rusty chains, take them off
Vanish into the night
Itss as if the era is
Leading me astray with a face hiding sorrow

Eiri's creepy lyrics:
The dimension of the panorama
That has slipped out of sight
The perfect camouflage simply trembles
Seeking out secrets
You're cold but indecent and I want to see you
The floating sea of pleasure
That toys with me in a rainbow of colors
A game hemmed by shadows
Punch it out of this world
Kiss shining
Shaping solitude
The entangling remorse slices through the void
Make me shining
The shards of the heart that scatter
In the hope that passes by blindingly
Kiss shining
Pressing lips to your gaze
Even the flower petals beginning to melt
Get in the way
Kill me shining
At the ends of the colored thrills
There is an apparition that has begun to shine
Please don't cryin'
Shaping solitude
The entangling remorse slices through the void
Make me shining
The shards of the heart that scatter
In the hope that passes by blindingly
Kiss shining
Shaping solitude
The entangling remorse slices through the void
Make me shining
The shards of the heart that scatter
Into the hope that passes blindingly

Shuichi makes up lyrics for Eiri:
When and orange moonlit night comes along
It reminds me of you
My cool affected lines
Are lines that belong to someone else
I suddenly look up to see a silhouette
The light that lit your profile
Even now, that pale light
For what am I waiting?
The room empty of you
Time alone echoes in my sleepless heart
Like footsteps
Even now, I'm waiting
Alone, I'm stopped still
That moon we saw together that day!
Where are you seeing it form now?
Even now, I'm waiting
Alone, I'm stopped still
That moon we saw together that day,
Where are you seeing it from now?

End credits:
Oh! Oh! Smashing Blue! Oh! Oh!
At the rain trickling down my body
A fleeting emotion trembles
At the blazing red temptation
The wandering night ends in dawn
The smashing blue that colors the brilliant miracle
It starts, make me true
The vanishing moon is silent
The smashing blue has no need of even your voice
The glimmer lingering
On your bare skin is like twilight
Oh! Oh! Smashing Blue! Oh! Oh!
