Different from theoriginal 2009 release, this version of the soundtrack is the only one to be available in lossless, and also contains additional tracks.

Released to the public in 2017 after correspondence between a Reddit user and Alias Conrad Coldwood. Made available via a Reddit thread, hosted on MediaFire in 4 .zip files. Said version contains no artwork.
Also added in 2019 on Unproductive FunTime's website in the form of a torrent. However, it only contains the 37 tracks of the OFF soundtracks, and none of the bonus tracks (38~49) are enclosed in this torrent. It is also enclosed with a PDF which contains a front & back artwork, alongside the tracklist.

M01~37: OFF Original Soundtrack
M38~39: Le Roi Crapaud (Off FanGame) Original Soundtrack
M40~46: Prototype Music
M47~49: Unused Music

Composed by Alias Conrad Coldwood. "Pepper Steak" contains samples from "Pepper Steak" (by Washboard Rhythm Kings), "Caravan" (by Duke Ellington), "Just Gone" (by King Olivers Creole Jazz Band), "April in Paris" (by Glenn Miller) and "Donkey Serenade" (by Artie Shaw). "Rainy Day (And Meat)" contains samples from "Je Cherche un Millionaire" by Mistinguett. "Flesh Maze Tango" contains samples from "St. Louis Blues" (by Esquivel!) and "NGO" (by Ryuichi Sakamoto). "Windows Licking" contains samples from "Railroad Man" (by Ryuichi Sakamoto) and "Just Gone" (by King Olivers Creole Jazz Band).

"Peper Steak" is written as such in the files. But on the tracklist in the picture, it is "Pepper Steak".
