"I Better Go Now" is a blues song originally performed by Howlin' Wolf, a renowned blues musician from the 1950s. The song tells the story of a man who realizes that his partner has been wasteful and unfaithful with his money, leading him to contemplate leaving the relationship. The lyrics depict the narrator's frustration and anger towards his partner's actions. He mentions having money that was intended to buy them a home, but upon returning home, he discovers that the money has been squandered. This betrayal and financial irresponsibility create a sense of betrayal for the narrator. The repeated phrase, "I better go now, 'fore I get out my blade," suggests that the narrator is reaching his breaking point and may resort to violence if he stays in the situation any longer. The blade symbolizes both the narrator's anger and his desire to protect himself from further emotional harm. Furthermore, the mention of "so many people, dead and in the grave" indicates that the narrator has witnessed the consequences of letting anger and resentment consume a person, leading to potentially deadly outcomes. Overall, "I Better Go Now" showcases the theme of betrayal, financial irresponsibility, and the narrator's realization that he needs to leave the relationship before it leads him down a path of violence or further heartbreak.
