Copy lyrics

The clock stopped ticking forever ago
How long have I been up? I don't know
I can't get a grip but I can't let go
There wasn't anything to hold onto, though

Why can't I see, why can't I see
All the colors that you see?
Please can I be, please can I be
Colorful and free?

What the hell's going on? Can someone tell me please
Why I'm switching faster than the channels on TV?
I'm black, then I'm white - no! Something isn't right!
My enemy's invisible, I don't know how to fight

The trembling fear (Ah~) is more than I can take (Ah~)
When I'm up against (Ah~) the ECHO in the mirror (Ah~)
ECHO... (Ah~)

(Ah~) (Ah~) (Ah~)

I'm gonna burn my house down
Into an ugly black
I'm gonna run away now
And never look back

I'm gonna burn my house down (I'm gonna burn my house down)
Into an ugly black (Into an ugly black)
I'm gonna run away now (I'm gonna run away now)
And never look back (And never look back)

I'm gonna burn my house down (I'm gonna burn my house down)
Into an ugly black (Into an ugly black)
I'm gonna run away now (I'm gonna run away now)
And never look back (And never look back)

I'm gonna burn my house down (I'm gonna burn my house down)
Into an ugly black (Into an ugly black)
I'm gonna run away now (I'm gonna run away now)
And never look back (And never look back)

I'm gonna burn my house down
And never look back
And never look back
AND NEVER LOOK BACK

What the hell's going on? Can someone tell me please
Why I'm switching faster than the channels on TV?
I'm black, then I'm white - no! Something isn't right!
My enemy's invisible, I don't know how to fight

What the hell's going on? Can someone tell me please
Why I'm switching faster than the channels on TV?
I'm black, then I'm white - no! Something isn't right!
My enemy's invisible, I don't know how to fight

The trembling fear (Ah~) is more than I can take (Ah~)
When I'm up against (Ah~) the ECHO in the mirror (Ah~)
The trembling fear (Ah~) is more than I can take (Ah~)
When I'm up against (Ah~) the ECHO in the mirror (Ah~)

(Ah~) (Ah~) (Ah~) (Ah~) (Ah~) (Ah~) (Ah~) (Ah~)

Trivia

• While Circus-P was originally credited in-game as a composer and lyricist for ECHO, he has stated his wishes to be uncredited, as his work was exclusively in tuning GUMI's vocals. The credits have since been changed to only feature CRUSHER P.
• ECHO is the only song to be entirely sung in English by a SEKAI group.
• The number of notes in the HARD chart, 404, is an error code that means "page doesn't exist."
