Though the lyrics aren't the most enthralling part of the song, the simplicity is enough to drive the message home and, in the end, it's more about the bombastic vocals. Having a science lesson isn't very "algebraic" of Adventure Time, but the song still offers a great experience.

During a jam session with Finn, Marceline reveals her vulnerable side as they create the song "Fries." About more than the salty fried spuds, Marceline is singing about her estranged relationship with her father. Carrying the song's message of woe are the enchanting vocals, which remain somber throughout while hitting some heavier tones to relay the Vampire Queen's anguish.

The glimpse of a cartoon character's negative relationship with their parent is rare among cartoons and was a first for Marceline, making this song as unique as it is relatable. To avoid over analyzing this piece too much, the song simply gives fans a chance to release sadness for a brief and partially silly moment.

Fiona quickly became a very popular character, and watching her side story was a treat for the fans. Like how Finn falls for Princess Bubblegum, Fiona falls for Prince Bubblegum, but the latter's feelings are actually reciprocated. The romantic occasion is marked by Prince Bubblegum's song "Oh Fiona."

What really makes this song stand out are Neil Patrick Harris' incredible vocals. His singing as PB adds the right amount of softness to serenade the listener while he floats from one romantic line to the next. These words of love are sweet with a hint of the quirky humor that fans of the series have come to love. Though any sucker of romance is sure to adore this song, the Fiona/PB shippers love it most of all as the song cements the ship they're rooting for, even though it's all made up by the Ice King.

7 'Island Song' Is More Than Just An Ending Theme

Adventure Time is one of the few cartoons to have an original ending theme, but that's not what makes "Island Song" great to listen to. On its own, the carefree vibes coming from this song are a delight to listen to even for those who've never watched the series.

Upon a close listen, the song soothes the listener with a story of a chill adventure, which fits most of the series perfectly. In the lyrics, there is also the singer's promise that no matter how bad the journey becomes everything will work out.

In another episode following Fiona and Cake's adventures, the girls spend some time with Marshall Lee the Vampire King, and sing the song "Good Little Girl." Marshall Lee takes the lead, as usual, calling Fiona a "good little girl" and through the song questions why she would spend time with someone as "bad" as he is.

The song has a romantic melody to it, but romance seems to be hard to find when all Marshall can do is tease Fiona the entire time. Putting aside these characters' up and down relationship, the song itself is a delight as the melody pulls the listener into a slow dance of romantic tension.

Finally putting a confession together, Finn asks BP "what am I to you", hinting at his romantic feelings for her. Regardless of what her answer would be if they weren't focused on the magical door, Finn proceeds to use the performance as a way to express what all his friends, including BP, mean to him. "My Best Freinds in the World" is a unifying moment for the characters who, before this episode, weren't as close. It makes their adventures going forward that much more meaningful and the harmonies they share on their own are enchanting to listen to.

In order to open a magical door standing in their way, Finn, Jake, Princess Bubblegum, BMO, and Marceline have to create music together. Their first attempt to open the door becomes the song "I'm Just Your Problem," sung by Marceline.

To many fans' delight, Marceline sings about PB, but when PB doesn't approve of the lyrics, the song changes into the vampire's release of pent-up frustrations. The magical door reacts to the truth of Marceline's true feelings for PB as Marceline belts out a heart-wrenching melody that has become one of the series' most iconic moments.

Looking to create music to woo princesses, The Ice King enlists the help of Marceline, whom he doesn't realize he has a history with. At the time this episode was released, the fans had no idea what Marceline or the Ice King's shared background was, but their song "Remember You" would be the reveal.

Although The Ice King's vocals are pretty bad, that surprisingly doesn't take away from how powerful the song is. Part of his charm in this song is that he really doesn't understand why Marceline is so emotional about seeing him, but as she has him read his own journal entries to their somber melody it becomes clear, this moment is a huge reunion for the two of them.

1 'Everything Stays' Is An Poetic Masterpiece

The soft melody hits emotional peaks at just the right moments to support the song's message of finding a way no matter how terrifying the challenge may be.

The lyrics reflect how wild life can be as it bounces between being predictable and unpredictable when least expected. The full package of this piece is a serenade of inspiration for anyone, like Marceline, struggling to find peace in life. Her singing this song in the end of her arc "Stakes" is a testament to how much she's grown.
