  "prompt": "Genre: Mandopop / R&B; BPM: 131; Key: D major; Rhythm: Pop-rock half-time backbeat on acoustic drums, consistent 16th-note hi-hats, creating a slow, melancholic ballad feel.; Instruments: Bright grand piano playing arpeggiated chords and melodic motifs; clean electric bass on root notes; acoustic drum kit; synthesized string section for pads and swells in chorus; subtle clean electric guitar arpeggios for texture.; Vocals: Male tenor, conversational and slightly mumbled in verses, becoming clear and emotional in the chorus. Delivery is characteristically behind the beat, with R&B-style phrasing.; Mood: Melancholic, pleading, regretful, nostalgic.; Production: Polished early-2000s studio sound. Vocals are upfront and clear. Wide stereo image, especially with strings. Moderate reverb creates a sense of space without being cavernous.; Highlight: The signature R&B-influenced, slightly behind-the-beat male vocal phrasing.",
