---

• The intro theme, "Back to Zero" sounds quite similar to "Once Upon a Time", yet gives off the impression that something's different.
• Here we go again. Flowey’s new theme feels like a reprise of "Your Best Friend", with 16-bit instruments in contrast to the 8-bit instruments of "Your Best Friend". The melody of "Finale" is used during the second half of the song. The theme is notably more upbeat, reflecting the fact that Flowey’s friendly facade is a long-term plan this time.
• "Stay Determined!", Asgore's equivalent of "Fallen Down", is a warm, gentle yet regal-sounding arrangement of "Determination".
• The new Ruins theme gives off a sense of warmth and comfort. Rather than using the original Ruins Leitmotif (which is instead used for Undyne), this theme used Asgore’s motifs, with a bit of "Your Best Friend" thrown in, representing Flowey pushing Frisk along.
• "Ain't Afraid", Napstablook's boss theme, is a catchy, upbeat dance remix of "Ghost Fight", perfectly fitting the lighthearted performance Frisk and their new friend Blooky put on in the Ruins.
• "Regret", Asgore's boss theme. A much grander take on a Heartache-style song.
• "A Desperate Plea + Righting Wrongs", the theme that plays during at the end of Asgore's fight, mixes together "Small Shock", Asgore's normal theme, and Frisk's leitmotifs ("Reunited" and "Stronger Monsters") for a somber, yet hopeful and uplifting piece.
• Your Theme, Frisk's theme, has a feeling of warmth and sincerity to it. The track was inspired by "Run away, Fugitives" from Pokémon Mystery Dungeon.
• "PAPYRUS, THE VERY COOL SCIENTIST!", a fittingly goofy and sciency-sounding track for The Great Papyrus.
• "heya.", Sans’s theme, has the same basic melody and laidback feel as "sans.", except played in a style reminiscent of "Nyeh Heh Heh!" from the original game, fitting the way the characters' roles have been swapped.
• Land of Ice and Snow, the theme for Snowdin, is based off of Land of Immortality from Bravely Default. The somber tone sets the stage for how much higher the stakes are in Inverted Fate compared to Undertale.
• Papyrus's battle theme, "THE GREAT PAPYRUS' INCREDIBLY COOL BATTLE SONG! (ALSO KNOWN AS BONETROUSLE!!!)" manages to capture both the feel of the original "Bonetrousle" while also reflecting Papyrus's focus on science. The fact it incorporates the trailer version of "Bonetrousle" is just icing on the cake.
• "Lazybones", Sans's fight theme (collab with Jimmy the Bassist and Keno), which incorporates "It's Raining Somewhere Else", "Heartache", "Bonetrousle", and even "Megalovania", which all work wonderfully in creating a serious-sounding theme that fits the dynamic of the battle it's used for whilst still feeling true to its counterpart song from the original game.
• The new Waterfall theme is an awe-inspiring reprise of the original. This track feels even more melancholic than its counterpart from the original game, due to the circumstances surrounding Waterfall in this new timeline.
• The IF equivalent of "Dogsong", best summed up by a quote from Papyrus.
  Papyrus: FRISK, IF THERE’S ONE THING YOU SHOULD KNOW... IT’S THAT THERE IS NO LOGIC. ONLY DOG.
• "Just an Act", a melancholy track that gives off a sense of emotional vulnerability and hopelessness. It plays when Frisk heavyheartedly confesses to Papyrus how they hide their insecurities under a charismatic facade. It also plays during Frisk’s visit to the Waterfall Incident’s gravesite and during Interlude 2. It later gets a Dark Reprise during the aftermath of the initial fight with Undyne in the CORE.
• "Heart to Heart", a soft, comforting track that gradually gets more uplifting. It plays when Papyrus reaches out to Frisk and empathizes with their insecurities, learning their name and reassuring them that they are not alone. It also plays at the end of Alphys's fight.
• Bratty and Catty’s themes, "Alley Girl" and "Dumpster Dueling" are gloriously catchy.
• "Danger! The Killer Robot Descends!", an over-the-top rock cover of "Metal Crusher". It plays during Mettaton’s fight in Waterfall.
• "Wavering Spirit", Alphys' battle theme. "Alphys" (song) fits surprisingly well with the style of "Spear of Justice", yet the theme has a more melancholy feel to it, reflecting the poor captain's inter turmoil.
• "Scientific Justice", a mashup of "Spear of Justice", "Another Medium", and "CORE" for Undyne's lab fight. The older version, while not quite packing the same punch, is still well-made.
• "The Heat is Rising! Undyne's Lava Domain!", the Hotlands theme. A frenetic tune that reflects the perilous nature of the Undyne’s puzzles. It is based off "Chaos Angel - Act 1" from Sonic Advance 3.
• While not yet completed, the Hotlands regular battle theme is pretty catchy, taking inspiration from Sonic the Hedgehog CD's "Metallic Madness".
• "Presents in the Past". A soft, sentimental remix of "Bonetrousle". It plays during the first part of Papyrus's date, when Papyrus tells Frisk the story how he met "Santa Claus".
• "Remembering the Sunshine", an emotional piece that brings to mind revisiting painful memories from a safe place. Inspired by "In The Morning Sun" from Pokémon Mystery Dungeon, it plays during the second part of Papyrus's date, when Frisk pours their heart out to him, confessing their painful backstory and telling Papyrus just how much he means to them.
• "Escalating Tension! CORE-nered at the Genesis of Determination!", the CORE theme. An intense track inspired by the final boss theme from Sonic the Hedgehog 3.
• "Voice of Reason" is a heartwarming theme based on the beta track of "Undertale" which plays whenever Chara is reassuring Frisk (or even the other way around).
• "Yes. Yes! YES!!! THE MAD MANNEQUIN GETS THEIR REVENGE!!!!", Mad Dummy's boss theme. A climactic techno remix of "Dummy!".
• "Soul-Splitting Fury! Mad Mew Mew’s Grand Debut", Mad Mew Mew’s boss theme, manages to sound even more frenetic and intense than its equivalent in the original game.
• "Stars Collide! Rise, Mettaton SPIRAL!" is a very over-the-top anime-inspired track fit for a star. Napstablook alludes to it in Part 23.
  Napstablook: oh, i’m working on a new song for mettaton. something fast, rockish. it’s for... something special... and top secret. but it should be cool. maybe it’ll even make him feel...
  Frisk: ...What is it?
  Napstablook: oh, nothing. don’t worry about it.
• "Say Your Prayers, Punk!", the theme that plays during the final showdown with Undyne (piloting The Determinator) at the end of the CORE. Inspired by "Battle of Providence (Phase 1)" from Bravely Second, this intense track perfectly reflects Undyne’s inner turmoil and her desperation to keep her promise. The remixes that play during the different stages are also good as the fight gets even more intense.
• Ultimatum and Everything is (Not) Fine, the themes that play during the boss fight with Frisk, convey the emotional tension as Sans, Papyrus, and Chara attempt to get Frisk out of their Heroic BSoD before they do something they'll regret.
• "Fate of the Fallen", the replacement for "Undertale". A beautiful mix of "Bonetrousle", "His Theme", "Reunited", "Once Upon A Time", the beta "Undertale" motif, and "Finale", among others. The older version, "Inverted Fate" stays closer to the style of its canon counterpart in terms of instrumentation.
• "Lament of the Last", the theme for The Mage/Kindness. A wistful original melody.
• "Bergkönigin + TORIEL." A beautiful "ASGORE" remix in its own right. The updated versions, "Heartbroken" and "Fallen Crown", dial the beauty and emotion up for a truly sorrowful and final theme.
• "You're GARBAGE!" and "Checkmate", the themes that play during the long-awaited showdown with Flowey at the barrier. An even more twisted remix of "Your Best Nightmare" interspersed with traces of "Bonetrousle", the beta "Undertale Motif", and Flowey's own maniacal cackle.
• "mus_reboot", The intro theme for the Final Arc. A dramatic track combining elements of "His Theme", "Undertale" , and "Your Best Friend", and an original melody at the end. Nothing Is the Same Anymore indeed.
• "mus_mirror" is another Dark Reprise of Frisk's theme that plays during their fight with Chara when the timeline is reset, exemplifying Chara's anger and grief over the current situation. "Your Best Friend" is also included, representing Flowey's involvement.
• "mus_hope", a Triumphant Reprise which plays in the fourth Null episode (appropriately titled "Hope") when Frisk and Chara discover that there are at least two monsters who managed to escape absorption.
• mus_bigdeal, Spamton's boss theme, mixes in the "Bonetrousle" and "CORE" leitmotifs into Spamton's "NOW'S YOUR CHANCE TO BE A" and "BIG SHOT" themes (as well as the "Null" leitmotif during the "freedom" leitmotif), emphasizing Spamton's weirdness and his association with Papyrus and Hotland.
• mus_effigy, the battle theme of the Effigy of Ego, is a slow paced track befitting of an angelic creature representing Asriel's god complex, and even has lyrics ^note ASRIEL will let us go. ASRIEL will save us all. ASRIEL will give us hope, overriding right and wrong. that play up Asriel as a god-like figure.
• mus_possessiveness is a variant of the already soothing-yet-unnerving mus_stay, but more discordant and filled with lyrics that embody Asriel's mindset.
  Chara come back
  Cut me some slack
  I made this place for you
  Don't be a brat

Unofficial tracks

• "PAPYRUS!" and "THE SONG THAT PLAYS WHEN YOU FIGHT THE GREAT PAPYRUS!!!" by Keno9988iv. Especially the latter, which keeps the Mega Man feel of "Song That Might Play When You Fight Sans".
• "One Shall Prevail" by Jamangar, for Genocide Sans. A menacing song that was actually inspired by Sean Evans's Backbone! The updated version by Doctorine is even more intense.
• "...WHY?" by Starfury, a final boss theme for Papyrus in the Genocide run. It's been remixed endless times despite its non-canon status, with possibly the greatest version being Jamangar's second take.
