Red lyrics= CL

Blue lyrics= Minzy

(ENGLISH)

Rock the base, r-r-rock the base
Scream! Ah ah ah ah~ ah ah ah ah ah ah ah~
Scream! Ah ah ah ah~ ah ah ah ah ah ah ah~
Scream! Ah ah ah ah~ ah ah ah ah ah ah ah~
Scream scream scream scream 
Scream scream scream scream
(Rock the base, r-r-rock the base)

(Minzy)
I’m bout to paint this town red, I’ll draw the line from here
Finally everyone’s come to party but you
Ah, ah, don’t listen and start meddling
I’ve had enough of it, I’m in control-trol-trol

(CL)

Just wanna keep dancing
With the same gaze
I’m flowing with the sways but I’m scared of what’ll happen
Giving up is the worst
So I’m eternally waiting
Don’t just selfishly say
“It’s not like I need you”

(Dara)

Bring it on
It’s full of mismatched scenarios
Turn it up
It shouldn’t be this mismatched
Because the truth is I want it all
I can’t hide my confusion~

Bom (Minzy & CL)

(Minzy & CL) It’s the same situation

(Bom)
There’s no such thing as “it has no meaning” so get away
I’ll fly away from (Minzy & CL) this situation again

(Bom) Come on, let’s get away 

(Rock the base, r-r-rock the base)
Scream! Ah ah ah ah~ ah ah ah ah ah ah ah~
Scream! Ah ah ah ah~ ah ah ah ah ah ah ah~
Scream! Ah ah ah ah~ ah ah ah ah ah ah ah~
Scream scream scream scream 
Scream scream scream scream
(Rock the base, r-r-rock the base)

(CL)
Everybody’s a novice, it’s time for a crowded floor
I’m so good you want to learn my ways,  I’m delicious
I’m charged with energy and young
Girls just wanna have fun
This dangerous excitement is forever-er-er? 

(Minzy)
I bite down at the
Wave of questions
I look at you biting down and charge my ego
Seriously, leave me alone
I wanna be jumping
Hey DJ, stop the fairytale songs and bump it!

(Dara)
Bring it on
If you don’t change then bye
Turn it up
If you change, I want to hear
Because the truth is I want it all
I can’t stop my heart from pounding~

Bom (Minzy & CL)

It’s this situation again
My memories with you will fade away
Eventually, I will fly away from this situation
Come on, let’s get away
(Rock the base, r-r-rock the base)

(CL)

I fell in love shamefully
“I’ll be careful next time”
So many times
I’ve sworn that so many times (sworn that so many times)

(Bom)

I fell in love with a man, a guy
“It won’t happen next time”
So many times
I’ve sworn that so many times~

Bom (Minzy & CL)

It’s the same situation
There’s no such thing as “it has no meaning” so get away
I’ll fly away from this situation again
Come on, let’s get away 

(Rock the base, r-r-rock the base)
Scream! Ah ah ah ah~ ah ah ah ah ah ah ah~
Scream! Ah ah ah ah~ ah ah ah ah ah ah ah~
Scream! Ah ah ah ah~ ah ah ah ah ah ah ah~
Scream scream scream scream 
Scream scream scream scream
(Rock the base, r-r-rock the base) 

If you want the link to the lyrics, let me know! 

Two things, the lyrics don't belong to me, they belong to 2NE1 and I give credit to the person who translated them from Japanese to English.

Oh, and if you haven't seen their music video for Scream, here it is!
