“Remember You” is a song written by Rebecca Sugar that Ice King and Marceline sing in “I Remember You.” The lyrics come from several messages Simon Petrikov (Ice King) wrote explaining to Marceline his deteriorating mental condition after the Mushroom War.

[Verse 1: Marceline & Ice King]
Marceline, is it just you and me in the wreckage of the world?
That must be so confusing for a little girl
And I know you're going to need me here with you
But I'm losing myself, and I'm afraid you're going to lose me too
Ooh, yeah, keep it goin'
Oh, um, oh
[Chorus: Marceline]
This magic keeps me alive, but it's making me crazy
And I need to save you, but who's going to save me?
Please forgive me for whatever I do
When I don't remember you
[Post Chorus: Ice King & Marceline]
Wow, I wrote that? Hot stuff
What? You don't remember what it means?
Look
[Verse 2: Ice King]
Marceline, I can feel myself slipping away
I can't remember what it made me say
But I remember that I saw you frown
I swear it wasn't me, it was the crown
[Chorus: Ice King & Marceline, Ice King]
This magic keeps me alive, but it's making me crazy
And I need to save you, but who's going to save me?
[Break: Jake & Finn]
What is goin' on in there?
I have no idea
[Chorus: Ice King & Marceline]
Please forgive me for whatever I do
When I don't remember you
[Outro: Ice King & Marceline, Ice King, Marceline]
Da-da
Da-da, da-da, da-da
Da-da, da-da, da-da (Da-da, da-da)
Da-da, da-da, da (Da)
