Meaning of "I'm Not Human At All" by Sleep Party People

The repetition of "I'm not human at all, I have no heart" can be interpreted as a reflection of emotional detachment and a sense of numbness. The back and forth between two parties, both claiming the same lack of humanity and heart, could symbolize a lack of connection and empathy in a relationship. It could also represent a state of dehumanization or feeling disconnected from one's emotions due to past experiences or trauma. The repeated self-blaming phrases, "It's my own fault" and "It's not your fault," further emphasize a sense of personal responsibility and guilt. Overall, the lyrics convey a theme of emotional emptiness and a struggle to connect with others on a deeper, more human level.
