What do we mean when asking what these song texts are about? It may mean we are looking for topics, considering each single song as a net of themes. Maybe one text is about the milkman and a boy and about love. We would consider certain words in the text as representation of these topics (maybe two of them). Bottle, white, milk, door could be seen as related to the milkman, kiss and forever and flowers to love and to the boy, too. For us humans, the work of relating words to topics or topics to texts is usually conceptual. We do not need to have a look into the real world, not even into texts, in order to see a relation between the color white and the front door once the milkman is named. The machine instead needs data, empirical evidence. Working its way through the texts, it could make a list of words and the single texts where they occur, maybe calculating the frequency of the word within the text and within the entire corpus of songs.

The literary quality of these texts is evident. If you have studied German literature, you cannot ignore the allusions not only to GDR songs and brothers Grimm, but also to Trakl and French Symbolism. But how can we analyze Rammstein texts? I want to make them read by the machine. The programming languages R and Python offer a lot of packages with interesting methods of getting into the texts. I am curious about how we can, by machine Learning, find something out.
