Well,first of who dosen't like Marceline's songs? If you don't,go sit in the corner and think about your life.Ok,he songs are amazing (thank you Rebecca Sugar!) and I especially "I'm just your problem". And I like how they aren't really metaphorical or cryptic but still sound awesome.To top it all of' they are sung by one of the awesomest singers ever! I mean probably anyone can make Marceline sound awesome,but Olivia Olson doe sit really well.The fact that she sings add to her awesome character.
