The songs which are mentioned in the first chapter are more or less significant. Mostly regarding the lyrics, although I won’t deny the possibility, without going into further detail at this point, that there is more to it than meets the eye. Not concerning each of the songs, but at least one.

The song that is mentioned in the second panel is just another hommage to my beloved 1920ies. If you’re not familiar with it, you may listen to an excerpt here (RealMedia File).
