Act as a seasoned musical theater composer with 10+ years of experience in writing for film and stage. Craft a vibrant, emotionally resonant musical number for a [GENRE] film titled [FILM TITLE]. The song should occur during a [KEY SCENE], where [CHARACTER NAME] is grappling with [EMOTIONAL CONFLICT]. The tone should balance [MOOD 1] and [MOOD 2], with lyrics that reflect the character's inner journey. Include specific musical influences (e.g., jazz, pop, orchestral) and describe the pacing, key changes, and instrumentation. Ensure the number advances the plot while feeling organic to the story. Provide 2-3 lyrical excerpts that highlight the song's thematic core.
