How do the characters' backstories affect their songs?

The choice that states the songs express personal histories, showcasing motivations and dreams, is the correct answer because the characters in "Ride the Cyclone" each have unique backstories that deeply influence the content and emotional depth of their songs. Each character's experiences, desires, and struggles are reflected in the lyrics and themes of their respective performances, allowing the audience to gain insight into their voices and how those experiences shape their current perspectives. This connection between their past and their musical expression demonstrates the significance of their histories, as these elements drive the narrative forward and reveal the complexities of their individuality.

In contrast, the other options suggest a disconnection between the characters and their music, which does not align with the show's intent. The narrative is built around the idea that understanding these characters' backgrounds is essential for grasping their motivations and the essence of their songs, making the suggestion that their songs are unrelated to their histories inaccurate.
