  "prompt": "Genre: Neo-Soul, Psychedelic R&B; BPM: 68; Key: D Major (with frequent use of Bm7 and Em7); Rhythm: Slow, lazy 6/8 swing groove with a behind-the-beat feel, driven by a syncopated, melodic bassline and a simple kick/cross-stick pattern; Instruments: Clean electric guitar (Strat-style) with heavy reverb and vibrato, playing jazzy chords and arpeggios; finger-style electric bass (P-Bass style, round tone); vintage-sounding live drum kit (dry cross-stick, deep kick, minimal cymbal wash; Vocals: Male high tenor with a smooth, slightly grainy timbre, effortlessly switching between a gentle conversational tone and an ethereal, soaring falsetto; features intricate melismatic runs and lush background vocal stacks; Mood: Introspective, romantic, dreamy, and melancholic, evoking a sense of timeless love and comfortable solitude; Highlight: brain-scratching melodic hook created by the lead vocal's syncopated phrasing against the slow, triplet-based groove.",

  "lyrics": "[Intro]\n(Inst: Clean elec gtr w/ reverb, Finger-style bass, Vintage drum kit, Organ pad)\n(Mix: Full baseline—warm analog saturation, deep sub-bass, clean mids, silky highs. Wide stereo image with guitars panned. Deep plate reverb on all elements for cohesive space. Vocals front and center.)\n(Chords: Dmaj7 - Bm7 - Em7 - Gmaj7/A)\n\n[Verse]\n(Melody-Contour: Mostly stepwise, conversational, with small melodic turns at end of phrases)\n(Melody-Rhythm: Relaxed, spoken-word feel, syncopated against the 6/8 groove)\n(Vocal-Perf: Gentle, close-mic'd chest voice, almost a whisper, with soft edges)\n(Inst: Sparse groove; guitar plays arpeggiated chords, bass plays simple root notes, drums hold a steady cross-stick pattern)\n(Chords: Dmaj7 - Bm7 - Em7 - Gmaj7/A)\nLeft the window cracked\nCold air finding me\nSomewhere in the sheets\nStill holding your shape\nI don't rush the day\nLet the hours blur\nYour voice on the edge of a dream\n\n[Pre-Chorus]\n(Melody-Contour: Ascending melody building tension towards the chorus)\n(Vocal-Perf: Voice gains slight intensity and breathiness)\n(Inst: Bass becomes more melodic, fills between vocal lines)\n(Chords: Bm7 - Em7 - Gmaj7 - A7sus4)\nI'm not good at asking\nBut I keep on coming back around\nSo deep so deep\nEvery reason I have found\nForever feels like now\n\n[Chorus]\n(Hook-DNA: The phrase \"My blue jeans\" lands on a high, sustained note, creating an emotional peak; the syncopated rhythm of the following line \"Will last me all my life\" is the core earworm.)\n(Melody-Contour: Jumps up an octave to a soaring falsetto, then descends gracefully)\n(Melody-Rhythm: Long, sustained notes followed by a rhythmically complex, syncopated phrase)\n(Vocal-Perf: Shifts from chest to powerful, yet airy, falsetto. Lush background vocal stacks enter, harmonizing.)\n(Inst: Full band enters, cymbals open up slightly, organ becomes more present)\n(Mix: Wider stereo field, vocal stacks panned left and right)\n(Chords: Dmaj7 - Bm7 - Em7 - A7)\nSlow burn\nCarries me through\nThe night\nAll I need\nStay close\nI've got nowhere\nElse to be\nRight here\n\n[Verse]\n(Melody-Contour: Returns to lower, conversational register)\n(Melody-Rhythm: Slightly more rhythmic confidence than the first verse)\n(Vocal-Perf: Maintains the intimate, close-mic'd delivery)\n(Inst: Guitar adds subtle melodic fills in the gaps)\n(Chords: Dmaj7 - Bm7 - Em7 - Gmaj7/A)\nTuesday tasted grey til your name came through\nJust a text but it shifted the room\nI'd been keeping quiet folding all my edges in\nTrying not to need too soon\nSomething in the static\nPulling me across the distance\nI was never built for easy love\nSo I took the long way up\nForever feels like now\n\n[Chorus]\n(Hook-DNA: The phrase \"My blue jeans\" lands on a high, sustained note, creating an emotional peak; the syncopated rhythm of the following line \"Will last me all my life\" is the core earworm.)\n(Melody-Contour: Jumps up an octave to a soaring falsetto, then descends gracefully)\n(Melody-Rhythm: Long, sustained notes followed by a rhythmically complex, syncopated phrase)\n(Vocal-Perf: Soaring falsetto with more intricate ad-libs. Lush background vocal stacks are more prominent.)\n(Inst: More dynamic intensity from the full band)\n(Mix: Chorus hits with greater impact, parallel compression on drums)\n(Chords: Dmaj7 - Bm7 - Em7 - A7)\nSlow burn\nCarries me through\nThe night\nAll I need\nStay close\nI've got nowhere\nElse to be\n\n[Bridge]\n(Melody-Contour: Unpredictable, almost frantic melodic leaps, expressing desperation)\n(Melody-Rhythm: Phrases are fragmented and rhythmically disjointed, floating over the groove)\n(Vocal-Perf: Shifts to a strained, raw, high-register belt, full of emotion and vocal cracks)\n(Inst: Instrumentation becomes more chaotic and psychedelic; guitar uses more vibrato, cymbals become washier)\n(Chords: Gm7 - C7 - Fmaj7 - Bbmaj7 - Em7 - A7)\nI never said enough\nI never said enough\nAnd all that quiet love\nWas eating me up\n\n[Outro]\n(Vocal-Perf: Scatting and wordless vocalizations in a high falsetto, improvisational and free-flowing)\n(Inst: Instruments slowly fade out one by one, leaving the reverberating guitar and final vocal ad-libs)\n(Mix: Reverb tails become longer, creating a dream-like decay as the track fades to silence)\n(Chords: Dmaj7 - Bm7 - Em7 - A7)\nOooh lay lay loo\nOooh lay lay loo\nOooh wee oh wee oh\nWee oh wee\nLay loo lay loo lay\nOooh wee oh wee\nLay loo lay loo\nOooh wee\n",
  "cover_prompt": "Generate a minimalist ambient aura (Ambient Aura) image as a wordless music album cover. The core color palette and emotional tone of the image is: a dusky, melancholic wash of deep indigo bleeding into warm amber at the edges, evoking the last light of an evening that refuses to end — soft gradients of slate blue, muted gold, and faded rose merging without boundary, as though warmth and longing are held in the same breath. The image is composed entirely of pure color, rendered with extreme soft focus and heavy blur so that each hue transitions into the next with seamless, silk-like smoothness. The overall texture is supremely smooth and refined, with no imperfections. Strong requirement: this is a completely abstract modern Color Field work — absolutely no concrete objects, geometric patterns, or sharp edges. No film grain. The image must be a wordless cover — absolutely no text, pinyin, or Latin letters, and no human silhouettes. Convey an atmosphere of profound stillness, romantic melancholy, and infinite breathing space.",
