===The Warning===
This is the original album version. Beginning with a glitchy drum beat atypical of Year Zero, the guitar, synth and bass follow with a danceable melody followed subsequently by Reznor's vocals above the music. After Reznor declares "Your time is tick-tick-ticking away" for the first time in the song, the guitar plays a more distorted and 'industrial' sounding riff than the main riff. Reznor's final lyrical declaration continues repetitiously until the end, where he whispers "ticking away" faintly only for the music to be replaced by a short, quiet burst of static which ultimately leads into the following song, "[[God Given]]".
