[Intro: Björk, Björk & ROSALÍA]
Your mouth floats above my bed at night
My own private moon

[Verse 1: ROSALÍA & Björk]
Just because the mind can make up whatever it wants
Does it mean that it'll never come true?
Won't ever happen (Just because she can)
Please, could I change that?

[Chorus: Björk & ROSALÍA, Björk]
Is that the right thing to do?
Oh, I just don't know
I just don't know
Is that the right thing to do?
Oh, I just don't know
I just don't know

[Verse 2: Björk & ROSALÍA]
Let me introduce one to the other
The dream and the real, get them acquainted
Just because she can
Introduce
Just because she can
A mouth to a mouth
[Chorus: Björk & ROSALÍA, ROSALÍA, Björk]
Is that the right thing to do?
Oh, I just don't know
I just don't know
Is that the right thing to do?
Oh, I j-just don't know
I just don't know

[Bridge: Björk, ROSALÍA, Björk & ROSALÍA]
Can I just sneak up from behind
To the back of his head?
Then I lift up his hair
And nibble ever so lightly
That's where the hair starts
Just because she can
Now please, can I kiss him?
(Just because she can)
Yo quiero besarle
(Just because she can)
Come on, please, can I kiss him?
(Just because she can)
I just don't know, oh

[Outro: Björk, Björk & ROSALÍA]
Just because she can (Can)
There's a line there, I can't cross it (Ooh)
Just because she can
There's a line there, I can't cross it (Come)
Just because she can
There's a line there, I can't cross it
Just because she can (Oh, it must come)
There's a line there, I can't cross it
There's a line there, I can't cross it (Oh, just)
There's a line there, I can't cross it (Oh)
There's a line there, I can't cross it (Come)
There's a line there, I can't cross it
