  "lyrics": "[intro]\n(Chords: Cbmaj7 - Db7 - Gbmaj7 - Ebm7)\n(Sound-Design: DJ vocal drop, atmospheric synth swells, tape hiss)\n(Vocal-Perf: Spoken word, conversational, filtered)\n\n[verse]\n(Chords: Gbmaj7 - Ebm7 - Cbmaj7 - Db7)\n(Transition: Clean beat drop)\n(Inst: Full trap-influenced R&B beat enters with deep 808 bass, sharp clap, and fast hi-hats. Warm synth chords form the foundation.)\n(Melody-Contour: Rhythmic and conversational, with small melodic lifts at the end of each line.)\n(Melody-Rhythm: Highly syncopated, mirroring natural speech patterns.)\n(Vocal-Perf: Intimate, breathy, close-mic'd lead vocal. Very dry and upfront.)\nPacked a bag at midnight\nleft the key beside the door\nCity looked like diamonds\nnever noticed that before\nGot a table set for one now\nordered everything I want\nAnd the silence in the apartment\nain't a ghost — it's my font\n\n[chorus]\n(Chords: Gbmaj7 - Ebm7 - Cbmaj7 - Db7)\n(Inst: Arrangement remains consistent, focusing on the strong groove. Subtle shimmer pad added for width.)\n(Hook-DNA: Highly repetitive, descending three-note motif on a simple rhythmic phrase, creates an instantly memorable earworm.)\n(Melody-Contour: Simple, descending, chant-like melody that is easy to sing along to.)\n(Vocal-Perf: Lead vocal becomes slightly more projected. Light, airy backing harmonies are introduced, creating a fuller vocal texture.)\nJust me, just me\nnobody's compromise\nJust me, just me\nno more apologize\nI'm the loudest in the room\nwhen the room is only mine\nJust me, just me\nand honey I am doing fine\n\n[verse]\n(Chords: Gbmaj7 - Ebm7 - Cbmaj7 - Db7)\n(Inst: Groove continues unchanged, maintaining a steady, confident energy.)\n(Melody-Contour: Follows the established conversational pattern but introduces slightly more melodic movement.)\n(Vocal-Perf: Stays intimate and breathy, with soft, layered ad-libs and harmonies punctuating the lines.)\nUsed to read the room before\nI'd even say a word\nNow I walk into the venue\nlike my entrance is preferred\nPut my number in my own phone\njust to see it light up bright\nTurns out I've been the main character\nthe whole entire night\n\n[chorus]\n(Chords: Gbmaj7 - Ebm7 - Cbmaj7 - Db7)\n(Inst: Identical to the first chorus, reinforcing the main hook.)\n(Hook-DNA: Repetitive descending three-note motif, now with more prominent and complex backing harmonies.)\n(Melody-Contour: Descending chant-like melody.)\n(Vocal-Perf: Increased energy in the lead vocal. More elaborate ad-libs and layered harmonies weave around the main melody.)\nJust me, just me\nnobody's compromise\nJust me, just me\nno more apologize\nI'm the loudest in the room\nwhen the room is only mine\nJust me, just me\nand honey I am doing fine\n\n[bridge]\n(Chords: Gbmaj7 - Ebm7 - Cbmaj7 - Db7)\n(Inst: Beat and bass remain, but feel slightly more spacious to highlight the vocal melody.)\n(Melody-Contour: Shifts to more sustained, arching, and traditionally melodic phrases, building emotional weight.)\n(Vocal-Perf: Tone becomes more tender and reflective, a softer dynamic before the final build.)\nThere was a version of me\nwho kept her volume turned down low\nWore her edges smooth and careful\nanywhere she'd go\nBut I cracked the glass above me\nwith the weight of letting go\nAnd the ceiling was a mirror\nnow it's got my whole glow\n\n[outro]\n(Chords: Gbmaj7 - Ebm7 - Cbmaj7 - Db7)\n(Transition: Instrumental fades out slowly under vocals.)\n(Inst: Beat and chords continue as they begin a long, gradual fade.)\n(Vocal-Perf: A collage of ad-libs, repeating the main hook phrase with a feeling of finality and self-assurance.)\nJust me, just me\nJust me, just me\nJust me\nAnd I'm everything",
