The song "Neurotic" by Hundredth explores themes of self-deception, introspection, and the struggle to come to terms with one's own flaws and insecurities. The lyrics depict a person trying to escape from the overwhelming noise and chaos within themselves, choosing to deny their true feelings and instead pretending that everything is fine. They are unsure of whether they are making the right choices or if they are truly happy. The mention of "light up" and "blow it out" could refer to using a lighter to ignite and extinguish a flame, symbolizing the person's inner turmoil. The line "Neurotic, the flower burns" suggests that this internal conflict is destructive, slowly eating away at the individual's core. The repetition of "lie, lie, lie" represents the person's tendency to deceive themselves, refusing to acknowledge their true emotions or face their internal struggles. The repetition of "decompose" signifies the gradual deterioration that occurs when one continuously avoids confronting their issues. The final lines, "Until you decompose" and "Until you light up, no blow it out" imply that unless the person confronts their self-deception and addresses their inner turmoil, they will continue to suffer and decay emotionally. The song encourages the listener to face their insecurities and be honest with themselves in order to find peace and authenticity.
