"Let Me Know" by UB40 is about the frustration and impatience the narrator feels towards someone who is indecisive and unclear in their intentions. The song portrays the emotions of being stuck in a stagnant situation, waiting for the other person to make a move or communicate their needs. In the chorus, the narrator expresses their desire for clarity and understanding. They want the other person to inform them about what they have to do or what they want from the relationship. The use of "blow by blow accounts in black and blue" suggests that the narrator wants a detailed explanation, even if it may involve painful truths. The following verse reflects the narrator's impatience and the need to prioritize other things. They acknowledge the potential for commiseration but state that there are more important tasks at hand. The phrase "hurry up and wait" indicates the contrasting feelings of rushing to do something but being forced to pause and wait for the other person. The second chorus continues to emphasize the narrator's frustration and their inability to remember or connect with the other person's intentions. They ask for clarity and even suggest booking a future date for further discussion or negotiation. The final verse delves deeper into the problem at hand, presenting it as something beyond their immediate understanding or control. The horizon is a metaphor for an unseen obstacle or disagreement that prevents them from relating to each other. Consequently, they segregate themselves and wait for resolution. The overall message of the song conveys the narrator's yearning for open communication and understanding. They are tired of being in limbo, waiting for the other person's input. "Let Me Know" captures their desire for progress and resolution in their relationship.
