The lyrics employ metaphorical and figurative language, such as 'Du bist das Salz in meiner Wunde' and 'Du bist mein Kokain,' which require a solid understanding of idiomatic and symbolic expression beyond everyday usage. Vocabulary like 'Lethargie,' 'obszön,' and 'Plasma' used in a non-literal context adds complexity, demanding familiarity with abstract concepts. However, the overall sentence structures remain relatively straightforward and repetitive, preventing the text from reaching C1 complexity.
