Definitely gets the player pumped throughout the chaotic battle that is ULTRA GREED, Greed Mode's Final Boss.

The Dark Room's Final Boss gets the incredibly creepy "The Fallen Angel".The Chest's Final Boss receives "Ascension".The Chest receives a theme worthy of The Very Definitely Final Dungeon: "Sketches of Pain".While Sheol gets the disturbingly demonic "Duress".The Cathedral itself gets a nice, calming theme in the form of "Everlasting Hymn".There's an equally epic vocal track for Isaac's own boss fight: "Infanticide".The in-game version of "Hericide" is a bit different with a heavier emphasis on the drums, which makes it even more awesome. Satan (and Mega Satan) gets one of the most amazingly epic vocal tracks for his new battle theme: "Hericide".The theme of Mom's Heart/It Lives, "Ventricide", which periodically switches between intense and creepy in a heartbeat.Mom gets the fast-paced and frantic "Matricide" as her new battle theme, adding a strong sense of panic and urgency to the fight.While The Cellar has always been That One Level, "Periculum", the driving rock theme that plays as you battle through it, more than makes up for it."Crusade" is a rocking boss theme that prepares you for the various fights of this game.And it's creepy as hell! Made worse by the fact that it's called " Jesus Loves Me ".

It comes as a great surprise because it replaces the BGM that usually plays on that sequence.

It helps that it's the Background Music for the first level, so it's going to worm its way into your ears at one point or another. "Sacrificial", the Basement's theme, sets up the haunting atmosphere of the game quite nicely.Completely captures the sinister, yet bright tone of the game. The main theme (and arguably, Isaac's theme) of the game, "The Binding of Isaac".
