MPP
v5
Aggressive, riff-first hard rock with a mid-tempo BPM but double-time urgency, The band feels tight and relentless: punchy kick-and-snare drive, fast fills, and sharp stop-hits that snap sections into place, Guitars are the identity—high-gain, palm-muted precision in the verses, then wide power-chords in the choruses with a bright, cutting edge, Bass stays percussive and locked to the kick, mirroring the riff’s motion, The female lead is forward and intense: clipped rhythmic lines in verses, then a bigger open-hook delivery in choruses with tight doubles, Keep the mix dry, loud, and immediate; let the riff hooks and breaks create the drama, and make the solo melodic but fierce, always landing on a memorable motif

その日だけ、秒針が動いてなかった
v4.5
A Japanese jazz ballad unfolds with upright bass, brushed drums, and sparse jazz piano forming a fragile, irregular rhythmic base, A female vocal, breath-driven and melodically unpredictable, navigates between whispers, delicate phrasing, and sudden outpourings, Warm saxophone lines drift in and out, echoing emotional subtext, conversing with the voice in instrumental breaks and haunting silences, The structure is fluid, prioritizing nuanced timbre, texture, and space—eschewing pop conventions for an introspective, poetic jazz atmosphere, ‑Avoid rap, ‑spoken dialogue, ‑pop melodies, ‑symmetrical phrasing, ‑autotune, ‑idol-style vocals, ‑EDM elements, ‑or overly clean production, ‑Do not use male vocals, ‑Do not add hooks or catchy phrases, ‑Let rhythm be uneven, ‑phrases unresolved, ‑and silence present, ‑The saxophone must not be flashy or smooth—it should feel like breath, ‑not performance, ‑This is not a song for the stage, ‑It is a whispered novel carried by music
