The lyrics employ metaphorical and emotionally layered language, such as 'du bist das Leid, das mich glücklich macht' and 'die Sünde singt ihr letztes Lied,' which require a solid grasp of figurative expression beyond everyday usage. The vocabulary is moderately complex, including words like 'geschunden,' 'Fassaden,' and 'gewunden,' which may challenge learners below B2. However, the overall sentence structures remain relatively accessible and repetitive, preventing the text from reaching C1 complexity.
