  "prompt": "Genre: Nu-Disco, Synth-Pop, Dance-Pop, driving club anthem; BPM: 122; Key: A minor; Rhythm: Syncopated UK Garage/2-step verse groove abruptly shifting to a driving four-on-the-floor disco beat in the chorus; Instruments: Layer 1 (Melodic/Sample Core): Lush, evolving synth choir pads providing the main harmonic texture. Layer 2 (Rhythm Foundation): TR-909 four-on-the-floor kick with a plucky, sidechained Moog-style synth bass. Layer 3 (Harmonic/Production Glue): Expansive reverb washes, layered background vocal harmonies, and subtle arpeggiated synths; Vocals: Female, Dance-Pop Diva; breathy intro transitioning to rhythmic verses and a powerful, soaring belt in the chorus with signature R&B melismatic runs; Mood: Euphoric heartbreak (crying in the club); moving from melancholy to defiant celebration on a neon-lit dancefloor; Highlight: the dramatic tempo and genre shift from the slow synth ballad intro to the upbeat dance-pop verse.",
