All four books give lyrics, sheet music and guitar chords for Ju's songs. The songs range from very personal topics via book and media-related to eerie horror (-love) songs. Some of the melodies have been written by Katy Dröge, Rika Körte and Christine Hintermeyer. Artwork is done by Andrea Diener, Biggi Sauder and Sylvia Koch, and some by Yooh herself.
