I'm Just Your Problem

 is a song featured in the episode "What Was Missing." The song is written by Rebecca Sugar and sung by Olivia Olson (Marceline's voice actress), backed up by Finn (beatboxing), Princess Bubblegum (synthesizers), and Jake (viola). The song seems to be about Marceline's anger with Princess Bubblegum; the middle lines raise questions about her true feelings. It implies that her desire to reconcile and her frustrations are genuine. This is easily known as one of the most famous songs in the history of Adventure Time.

Chords
Em, Bm, C, G Ladadadada, I'm going to bury you in the ground, Em, Bm, C, G Ladadadada, I'm going to bury you with my sound. Em, Bm, C, G I'm going to drink the red from your pretty pink face, Em, Bm, C, G I'm going to-- (Marceline, that's too distasteful!) (Oh, you don't like that? Or do you just not like me?!)

Em, Bm, C, G Sorry I don't treat you like a goddess, Is that what you want me to do?

Em, Bm, C, G Sorry I don't treat you like you're perfect, Like all your little loyal subjects do

Em, B7, C, G Sorry I'm not made of sugar, Am I not sweet enough for you?

Em, Bm, C, G, Is that why you always avoid me? That must be such an inconvenience to you

C7, B7, Em, Cmaj7 Well, I'm just your problem I'm just your problem

C7, B7, Em, Cmaj7 It's like I'm not even a person, am I? I'm just your problem

Em, Bm, C, G Well, I shouldn't have to justify what I do Em, Bm, C, G I shouldn't have to prove anything to you Em, Bm, C, G I'm sorry that I exist, I forget what landed me on your black list Em, Bm, C, G But I shouldn't have to be the one that makes up with you

C7, B7, Em, Cmaj7 So, why do I want to? Why do I want to...?

Em, Bm, C, G To bury you in the ground... and drink the blood... from your... ugh!
