The song "Foetus" by Genetikk, featuring Karuzo, explores various themes and ideas. The lyrics depict the artist's self-perception and their role in the world. Karuzo starts by questioning his identity, describing himself as both the end and the beginning, the virus and the cure, the beggar and the legend. He represents the duality and complexity of human experience, encompassing both love and hate, past and future. He continues to describe himself as a fusion of human and machine, symbolizing the advancement and destruction brought about by evolution. He claims to embody progress and destruction, knowledge and ignorance, reality and illusion. Karuzo further explores contrasting concepts such as war and peace, lies and truth, birth and death. He presents himself as the devil's advocate, representing damnation and redemption, loyalty and betrayal. He goes on to claim that he is both a blessing and a curse, the first and last sentence in the book. He asserts his omnipresence, suggesting that he will be found when no longer searched for. He personifies addiction and ecstasy, as well as the descent and redemption found on the streets. As the lyrics progress, Karuzo describes himself as the voice in one's head, the puzzle and the solution. He mentions himself, along with his fellow artist Sikk Voodo, as a circus. The song concludes with Karuzo asserting his dominance and superiority in the German rap scene. He boasts about overthrowing the norms and rebelling against the mainstream. He sees himself as a living spectacle, with his own clone, seeking approval and recognition from others. Overall, "Foetus" delves into existential questions, exploring the complex nature of human existence and the artist's struggle for self-identity and recognition. It also reflects on the themes of duality, contradiction, and rebellion.
