''"'''Ruiner''''' " is the sixth track on ''[[The Downward Spiral (halo)|The Downward Spiral]].'' In 2004, a demo version was released with the Tenth Anniversary 2-disc Deluxe Edition of "The Downward Spiral."
===Song Credits===
This is the original album version.
===Ruiner (Demoversion)===Throughout this version, there are glitch effects of splicing up Trent's voice. The fast verses are louder and clearer than the studio version. The order of the two verses are reversed. The synth chorus is replaced by a more guitar driven one. ===Ruiner (demo)===
In this demo, the verses are almost whispered while the pre-choruses are sung in Reznor's lower-middle vocal range. The chorus is whispered rather than sung.
===Ruiner (version)===
Coming soon.
==Live==
''"Ruiner'' " was performed live on the [[Self-Destruct Tour]] but would be retired until 2007, when it was played again for the first time in almost 13 years.
