The lyrics employ figurative and metaphorical language, such as 'Im Feuer stirbt ein Engel' and 'der Wahnsinn in uns tickt,' which require a solid grasp of abstract expression beyond basic German. The vocabulary includes emotionally charged and somewhat elevated terms like 'Starrsinn,' 'Schutzgeleit,' and 'Feindflug,' which may challenge learners below B2. However, the sentence structures remain relatively straightforward and repetitive, preventing the text from reaching C1 complexity.
