Hell's greatest dad also plays a mean fiddle.
With ambitions to be a musical series, you can bet Hazbin Hotel is going to have beautiful music.
Pre-Series/Pilot
- A theme for Angel Dust known as "Slutty Spider Polka Pop
" was composed prior to the show's announcement, and it's fantastically made. It fits him so well that the Season 1 finale brings it back when Angel is protecting one of the Egg Boiz. - Charlie's beautiful opening rendition of "I'm Always Chasing Rainbows".
- "Inside of Every Demon Is A Rainbow," sung by Charlie (Elsie Lovelock) to sell her idea for a hotel that redeems demons to the denizens of hell. It's just as hilariously Glurge-y as the title implies... and just as awesome, especially when she hits the Patter Song stage of the piece. Courtesy of Parry Gripp.
- While it was unfortunately cut short, "Alastor's Reprise" takes Charlie's song, "Inside of Every Demon Is A Rainbow", and adds Alastor's own personal style and views to it, creating a stylish and jazzy Dark Reprise.
- "ADDICT", a duet between Angel Dust and Cherri Bomb that showcases the duo's carefree nature, but also sheds light on Angel's disturbing Dark and Troubled Past (or more accurately, his dark and troubled present).
Season 1
- "Happy Day in Hell" really nails Charlie's "Disney Princess of Hell" characterization, with Charlie singing about trying to appeal to the angels to support her hotel.
- "Hell Is Forever" is a Villain Song by Adam about how he doesn't believe anyone can change. Say what you want about the guy himself but the man can rock with the best of them!
- "Stayed Gone" is an awesome song with Vox and Alastor arguing live on the air. Notably, despite it being Vox's attempt to slander Alastor, the latter easily takes control of the song and ends with him winning.
- "It Starts With Sorry" is a sweet song where Charlie is trying to convince Sir Pentious to join the hotel... while Angel Dust and Vaggie want to beat him up for making Charlie wake them up with a musical number in the middle of the night.
- "Respectless" shows that - however much she might be a spoiled, bratty influencer - Velvette is genuinely observative and cunning, not only noticing that Carmilla clearly has something to do with the dead angel, but implying that she is aware of how she comes off to others, and uses her "acting respectless," as a tactic, infuriating her target until they slip up and reveal more than they'd like to - essentially, acting like a troll.
- "Whatever It Takes" is a beautiful Power Ballad and Distant Duet between Carmilla and Vaggie, singing about how they're doing whatever they can in order to keep those they love (Carmilla's daughters and Charlie). It's done in the style of an early 2000s-era Alternative Rock which only adds to the song's power.
- "Poison" is a sultry electropop song by Angel Dust that serves as a great Spiritual Successor to "ADDICT".
- "Loser, Baby" is a surprisingly sweet song where Husk tries to cheer up Angel Dust by pointing out they're both losers, and Angel isn't alone in his suffering.
- "Hell's Greatest Dad" is an utter gut buster of a Quarreling Song between Lucifer and Alastor over who would do better at helping Charlie with her goals. It's also in the style of electro swing, which fits Alastor's personality.
- "More Than Anything" is a beautiful duet where Lucifer and Charlie finally open up to each other about how much they want to get to know each other, and how much they love each other so deeply. It also reveals how the rift started, as Lucifer's failure to accomplish just what Charlie is trying to do was his Cynicism Catalyst, and he fears that her new attempt will draw Heaven's ire to the same degree (or worse) than his did. The reprise, this time sung by Charlie and Vaggie, is equally beautiful and is about how much they love each other and how, no matter what, Vaggie still believes in Charlie and her goal.
- "You Didn't Know" is a wonderful song, where all six major characters present get a role, that almost feels like it goes through phases while telling the story. Emily sings about trying to give sinners a second chance, until Lute and Adam interject and accidentally tell everyone about the exterminations. Sera tries to justify herself to Emily by singing how that knowledge was her burden to shoulder, but the latter retorts by having none of it. This leads to a powerful duet with Emily and Charlie that reprises "Hell Is Forever" while also serving as a MASSIVE "fuck you" to Adam and Sera, and then the song ends with Adam revealing to Charlie that Vaggie was an Exorcist.
- "Out for Love" is a badass and heartwarming expression of The Power of Love, in which Carmilla Carmine demonstrates both her musical and her combat talents while tutoring Vaggie and forcing her to improve her fighting tactics, explaining that keeping the ones you love in mind is essential for fighting to one's best abilities and winning a war. The song concludes with Vaggie finally regaining her angel wings and securing Carmilla's agreement to supply weapons capable of killing the angels, ensuring that the hotel will have a fighting chance.
- "Ready for This" represents Charlie becoming a much more assertive and persuasive leader after constantly being afraid of being too mean and hurting other people's feelings throughout previous episodes. She manages to rally the residents of Cannibal Town to join her fight to protect the hotel from Adam, when initially the cannibals were indifferent to her earlier speech. Charlie finally starts really feeling like an effective princess of Hell, is able to convince large numbers of strangers to follow her orders, gains the respect of Alastor and Rosie, and, coupled with the weapons Vaggie manages to persuade Carmilla to supply, is able to arm the hotel and have a real chance of defeating the angels and saving Hell.
- The "Finale" is a glorious conclusion to the first season, as the aftermath of the battle shows Charlie demoralized, but Lucifer and the rest of the hotel assure her that she's the first person in ten thousand years who has seen things differently and tried to offer the residents of Hell a chance of a better life, and that she has to continue on with her optimism. Lucifer admits that Charlie has inspired him to be more hopeful, and in sharp contrast to the situation in "Happy Day in Hell", when Charlie was virtually the only character who believed in the hotel's mission, and everyone else in Hell laughed at her, this time everyone pitches in to rebuild the hotel and is now sincerely convinced that the hotel has a worthy goal and that redemption is possible. The evolution in everyone's attitudes from the very beginning of the show to now is a reflection of how much Charlie has changed the lives and attitudes of the people around her, and how much her kindness and compassion have rubbed off on others. The song also includes verses from The Vees plotting to expand their influence over Hell now that the Exterminations are over and Alastor is seemingly out of the picture. Alastor himself has a Villainous Breakdown over being defeated by Adam and realizing the mysterious deal he struck with a then unknown party has limited his own power, so he starts planning to weasel his way out of the deal somehow.
