  "prompt": "Genre: Jazzy Lo-fi Hip-Hop; BPM: 101; Key: A major; Rhythm: Relaxed, heavily swung boom-bap groove with a behind-the-beat feel; kick on 1 and syncopated offbeats, snare on 2 & 4, lazy open hi-hats; Instruments: Detuned upright piano, Round soft kick drum, Clap/rimshot snare, Sizzly lo-fi hi-hats, Subtle sub-bass; Vocals: Female, breathy and gentle, intimate close-mic technique, almost spoken-word delivery, with light plate reverb and minimal EQ; Mood: The feeling of dozing off on a train, watching rain streak down the window as the city blurs by; Production: High-Fidelity, Pristine Radio-Ready Mix with expensive analogue warmth and silky smooth high-end, then filtered and degraded; Highlight: The entrance of the main detuned upright piano loop after the atmospheric intro; its brain-scratching melodic hook, with its gentle, imperfect tuning, immediately establishes the song's entire nostalgic world.",
  "lyrics": "[intro]\n(Mix: Mono-centric image, heavy side-chain compression ducking to kick, highs rolled off around 10kHz, prominent sub-bass foundation below 80Hz. Key effects: persistent vinyl crackle sample, subtle room reverb on piano.)\n(Inst: Filtered water sounds, Vinyl crackle.)\n(Chords: Ambient)\n(Instrumental)\n\n[verse]\n(Hook-DNA: Piano motif uses a simple dotted-eighth + sixteenth rhythm starting on beat 1; circles around the major 7th and 5th of the tonic; repeats 4 times before a simple descending resolution.)\n(Melody-Contour: Gentle arch shape, starts on 5, rises to M7, descends back to 3. Signature interval is the recurring major 7th.)\n(Melody-Rhythm: Phrases land squarely on downbeats, very relaxed, lagging slightly behind the kick drum's attack.)\n(Inst: Detuned upright piano, Lo-fi drum kit (soft kick, clap-snare), Round sub-bass.)\n(Chords: Aadd9 - Dmaj7 - F#m7 - E7)\n(Vocal-Perf: Soft, breathy, almost spoken, minimal dynamic change.)\n(Instrumental)\n\n[interlude]\n(Transition: Low-pass filter sweep down.)\n(Inst: Detuned upright piano (solo), Sub-bass sustains, Vinyl crackle more prominent.)\n(Chords: Aadd9 - Dmaj7 - F#m7 - E7)\n(Vocal-Perf: Wordless, hazy vocal pads, layered harmonies.)\n(Instrumental)\n\n[verse]\n(Transition: Drums re-enter without a fill, just landing back in the pocket.)\n(Hook-DNA: Piano motif uses a simple dotted-eighth + sixteenth rhythm starting on beat 1; circles around the major 7th and 5th of the tonic; repeats 4 times before a simple descending resolution.)\n(Melody-Contour: Gentle arch shape, starts on 5, rises to M7, descends back to 3.
