  "prompt": "Genre: Orchestral Pop / J-Pop Ballad; BPM: 87; Key: B Major; Rhythm: Modern, swung hip-hop beat with a half-time feel and skittering 16th-note hi-hats, providing driving pocket syncopation against lush legato strings.; Instruments: Programmed trap drums, deep sub-bass, close-mic'd acoustic guitar, grand piano, cinematic string section; Vocals: Male high tenor with a clear, emotive tone, shifting from gentle verse delivery to powerful chest belting in the chorus; features lush background vocal stacks.; Mood: Finding a faded photograph in an old coat pocket on a rainy afternoon, the world outside muted and grey.; Production: High-Fidelity, Pristine Radio-Ready Mix with expensive analogue warmth and silky smooth high-end. Vocals are forward, with ultra-wide orchestral elements and a tight, punchy low-end foundation.; Highlight: the punch of the full hip-hop beat re-entering on beat one of the second verse (1:37), after the chorus decays into a solitary, reflective acoustic guitar.",
