Suno prompt
A restless metal track with high energy and a swung feel at 158 BPM. The low end is electric bass playing root-note anchored, under an acoustic drum kit with a rimshot-forward snare and washy crash-led cymbals. Clean electric guitar carries the harmony, fingerpicked. The arrangement follows intro-verse-chorus-outro. A gritty male vocal delivers a raw and unpolished performance. Subtle bitcrush adds texture, with a slapback delay on the vocal. Mixed in a lo-fi and saturated style, foregrounding vocal clarity and melodic lead, built on chromatic and shifting chords, leaving a tense and coiled atmosphere.
Paste this into Suno's style field. It describes the sound only — adjust anything that does not match what you are after.
