"Fault Line" by Jack River is a deeply emotional and introspective song that delves into themes of regret, missed opportunities, and the consequences of one's actions. The lyrics suggest that the protagonist has been talking to themselves and reflecting on their past mistakes. They describe following words in their garden, which can be interpreted as following their own thoughts and introspection. The mention of burning flowers turning back to the sun symbolizes the pain and growth that comes from introspection and self-realization. The chorus emphasizes the regret of not loving someone the first time, acknowledging that the person they should have loved was bright but they were blind to it. This could refer to a missed romantic opportunity or failing to appreciate and cherish someone in their life. They express remorse for leaving this person on their "fault line," implying that they caused damage or hurt through their actions or negligence. The second verse adds further complexity to the emotions expressed in the song. The protagonist questions whether their heavy heart of gold, something precious and valuable, is worth dying for or lying for. They reflect on their self-destructive behaviors, seemingly walking away from themselves and towards their only fear, potentially indicating a pattern of sabotaging their own happiness. The bridge of the song describes a chaotic and cold city setting, where the protagonist is constantly falling in and out of situations. They can only hear the hands of the person they left behind, possibly indicating that they are haunted by the memory of this person and the missed opportunity for love. The song concludes with a repetition of the chorus, once again expressing regret for not loving this person the first time and leaving them on their fault line. The lyrics suggest a realization of their own faults and the pain caused by their actions. Overall, "Fault Line" is a deeply introspective song filled with regret and self-reflection. It explores the consequences of missed opportunities and the emotional turmoil that comes with realizing the weight of one's own actions.
