LSD and Remixes is a CD released simultaneously with LSD: Dream Emulator and Lovely Sweet Dream[1]. It's not exactly the original soundtrack because it contains no music heard durning gameplay. However, tracks from the album can be heard in the game's cutscenes. For example, the last track, "Come On And (Out Ass Mao Remix)", is featured in the game's opening sequences[2].
