Unofficial releases like System Of A Down - The Ultimate Rarities (a 2024 compilation on Discogs) and various Russian-made compilations have circulated in MP3 320 kbps format. These often include soundtrack appearances (such as their cover of "Metro" for Dracula 2000 or "Will They Die 4 You" from Chef Aid: The South Park Album ), live recordings, and other rare material. While these are not official releases, they form part of the comprehensive "discography" that many fans seek.
