In "La's Orchestra Saves the World," the protagonist holds a strong belief in the transformative power of music, feeling that it can positively influence the world's mood. This conviction, while seemingly illogical, drives her choices in music without any critical examination of its validity. She embraces her conviction wholeheartedly, selecting pieces that convey themes of structure and serenity.

Her musical selections reflect her desire for harmony and restoration; she turns to the works of composers like Bach, symbolizing order, and Mozart, associated with healing. This illustrates her deep connection to music as a source of comfort and change in tumultuous times.
