Integration

Motifs
Along with the basic Risk of Rain motif that is found throughout both soundtracks, a number of songs also borrow motifs from the first Risk of Rain soundtrack, or even other songs in and outside of Risk of Rain 2:



Trivia

 * Köppen As Fuck was added with the Scorched Acres update. The name of the song may be a reference to the "Tropical Rainforest Climate", which is designated as "Af" in the Köppen climate classification (Köppen Af).
 * The Raindrop that Fell to the Sky was added with the Skills 2.0 update.
 * A Glacier Eventually Farts (And Don't You Listen to the Song of Life) was added with the Hidden Realms update. The voice featured on the track (but not present in-game) is the one of Werner Herzog from the "making-of" documentary film Burden of Dreams (1982). The sampled dialogue is not featured in-game, and this instrumental version is a bonus track on the soundtrack. The name of the track is a quote from Werner Herzog's Minnesota Declaration.
 * The Dehydration of Risk of Rain 2 was originally titled The Dehydration of Risk of Rain 2's Main Theme by the Composer Chris Christodoulou up until the 1.0 update. Christodoulou explained that the song's title was shortened as some distribution platforms may return errors if a song title includes the artist's name in it.
 * Antarctic Oscillation and The Rain Formerly Known as Purple were added with the Artifacts update. The latter was initially called The Rain Previously Known as Purple.
 * The Rain Formerly Known as Purple features two motifs from Prince's Purple Rain, and features a similar outro.
 * Through a Cloud, Darkly, You're Gonna Need a Bigger Ukulele, ...con lentitud poderosa and Lacrimosum were added with the 1.0 update.
 * Nocturnal Emission was previously used on Sundered Grove before the release of Survivors of the Void.
 * In a first for the franchise, Prelude in D flat major and Who Can Fathom the Soundless Depths? are the first songs that are not composed by Christodoulou, but are rather his arrangements of Frédéric Chopin's Prelude Op. 28, No. 15 (appropriately named the "Raindrop" prelude).
 * The main melody of Risk of Rain 2 and The Dehydration of Risk of Rain 2 is adapted from the melody of "The Ghost Writer" from Alexandre Desplat's score for the film of the same name.
 * The ending of Terra Pluviam is an adaptation of the opening chords of "Mission to the Asteroid" from Michael Land's score 1995 game The Dig, made to fit the RoR2 sound pallette.
 * The Rain Formerly Known as Purple incorporates an arpeggiating piano motif and an ascending guitar motif from "Purple Rain", a song by the late artist Prince. The outro to both songs are also similar, including the use of piano and cymbals. The song also uses manipulated samples of the electric piano and clarinet from Chanson d'Automne from RoR.
 * A Glacier Eventually Farts samples the outro of Coalescence from RoR at around 2 minutes in.
 * Out of Whose Womb Came the Ice? contains a breif section of the RoR song "Arctic Oscilation"
