Exponential Entropy comes from Final Fantasy XIV and plays during the Cruise Chaser encounter in the Alexander raid series, composed by Masayoshi Soken. Its vocoded lyrics and relentless electronic arrangement set it apart from traditional orchestral boss music, giving the mechanical boss a cold, futuristic voice. Clips of the chorus later circulated as ringtones and short edits, where fans use the recognizable hook to signal speed, pressure and escalating chaos in gameplay videos.
