  "lyrics": "[intro]\n(Mix: High-fidelity, pristine radio-ready mix with expensive analogue warmth and silky smooth high-end. Prominent sub-bass, wide stereo image on synths and FX. Vocals are upfront, compressed, with layered reverbs and delays.)\n(Inst: Filtered atmospheric synth pad, subtle reversed SFX.)\n(Vocal-Perf: Female, spoken word, distant, heavily processed with a telephone EQ.)\nThey all want in\nBehind the velvet rope\nWhere the lights are sharp\nAnd the air tastes like smoke\n\n[verse]\n(Melody-Contour: Ascending, stepwise melodic lines that build tension into the pre-chorus.)\n(Melody-Rhythm: Syncopated, conversational phrasing against the steady beat.)\n(Inst: Main groove enters. Pulsing sawtooth bassline, dry 808 kick, sharp snare, closed hi-hats.)\n(Vocal-Perf: Male lead, smooth high tenor, effortless delivery with subtle falsetto inflections.)\n(Chords: Cm - Ab - Eb - Bb)\nHe traded everything he had for an image\nSigned his name away at twenty for the privilege\nNow the penthouse walls are closing in, ooh\nEvery smile he wears is borrowed, paper-thin\nOh, oh-oh-oh, I watched him disappear (Oh-oh)\nSold the version of himself they want to hear (Oh-oh)\nChasing validation, year after year (Oh-oh)\nGlass reflecting someone he no longer sees, oh-yeah, oh-yeah\n\n[chorus]\n(Hook-DNA: Repetitive, heavily rhythmic one-word motif, landing on syncopated 8th-notes, creating an infectious pop earworm.)\n(Melody-Contour: Ascending phrase that climaxes and resolves on the main hook word.)\n(Melody-Rhythm: Driving, insistent rhythm that contrasts with the smoother verse.)\n(Inst: Lush background synth pads and a subtle lead synth melody are added. More layers of vocal textures.)\n(Vocal-Perf: Male lead with increased intensity, supported by lush background vocal stacks.)\n(Mix: Stereo field widens significantly. Parallel compression added to drums for more punch.)\n(Chords: Cm - Ab - Eb - Bb)\nCaged inside a life he built for golden\nAll his principles are golden\nEvery promise comes out golden\nEven silence gets sold golden\nGolden, everything turns golden\nWatch him burn because it's golden\nBleed it dry to keep it golden\nCan't step back once you go golden\n\n[verse]\n(Inst: Beat remains consistent, synths slightly more subdued to emphasize the vocals.)\n(Vocal-Perf: Male rap, aggressive ad-lib style, heavily layered, panned wide.)\n(Mix: Rap vocals heavily compressed with short delays creating a rhythmic echo.)\nRolls on the driveway, deals in the daylight (Uh-uh)\nRolls on the driveway, deals in the daylight (Uh-uh)\nCameras follow me 'cause I stay relevant (Uh-uh)\nCameras follow me 'cause I stay relevant (Uh-uh)\n\n[verse]\n(Inst: Bass and drums are the primary focus. Synth pads are atmospheric and low in the mix.)\n(Vocal-Perf: Female, breathy, low-register, confident, half-sung/half-spoken delivery.)\n(Mix: Female vocals treated with a longer, darker reverb and more spacious delay than the male lead.)\nI learned how to vanish in a crowded room\nWore a different name like a designer costume\nFed them what they wanted, felt the bruise\nAnd I burned the girl I was to pay my dues\n\n[bridge]\n(Inst: Main drums drop out, replaced by a filtered percussion loop and a prominent arpeggiated synth.)\n(Vocal-Perf: Male rap, rhythmic, chanted flow, building energy.)\n(Mix: Build-up created with a rising low-pass filter sweep on the master.)\n(Sound-Design: A reversed cymbal swell transitions into the final chorus.)\nEvery room I enter gets a little colder\nEvery deal I close puts distance on my shoulders\nRolls on the driveway, deals in the daylight\nCameras follow me 'cause I stay relevant\n\n[chorus]\n(Hook-DNA: Repetitive, heavily rhythmic one-word motif, landing on syncopated 8th-notes, creating an infectious pop earworm.)\n(Melody-Contour: Ascending phrase that climaxes and resolves on the main hook word.)\n(Inst: Full instrumentation, all layers present. Ad-libs from the rap verse are woven underneath.)\n(Vocal-Perf: Male lead at maximum intensity, powerful and layered, with rap ad-libs providing counter-rhythm.)\n(Mix: Widest and most dynamically compressed section of the song.)\n(Chords: Cm - Ab - Eb - Bb)\nCaged inside a life he built for golden\nAll his principles are golden\nEvery promise comes out golden\nEven silence gets sold golden\nGolden, everything turns golden (Uh-huh)\nWatch him burn because it's golden\nBleed it dry to keep it golden\nCan't step back once you go golden\n\n[outro]\n(Inst: Deconstructed beat elements, with the pulsing synth bass and a single synth pad lingering.)\n(Vocal-Perf: Chopped and delayed vocal phrases from the chorus fade out.)\n(Sound-Design: A final filter sweep down and a subtle tape-stop effect concludes the track.)",
