How to Make Metal in Suno AI That Doesn't Sound Plastic

If your Suno metal tracks come out flat, weak, or obviously "AI", the problem is almost always the prompt. Suno is very sensitive to wording. This is the complete, no-fluff guide to writing metal prompts that actually hit — deathcore, metalcore, djent, groove, thrash, death and black metal.

1. Keep the Style field short (~120 characters)

The Suno "Style of Music" field works best with about 10–12 tags max. Past that, Suno "checks out" and ignores details like tempo. Lead with the most important info:

Genre first (1–2 max): deathcore, djent, groove metal
Tempo early: 180 BPM, fast tempo — putting BPM near the front makes Suno respect it.
Then drums, vocals, guitar tone, mood — comma-separated, never full sentences.

2. The winning tag order

[Genre] · [Tempo/BPM] · [Drums] · [Vocals] · [Guitar tone] · [Mood]

Example: deathcore, 180 BPM, blast beats, guttural growls, drop B tuning, crushing and heavy. Tight, ordered, under 120 characters.

3. Use structure tags in the Lyrics box

Section tags like [Verse], [Chorus], [Breakdown] go at the top of the Lyrics field, not the Style field. Suno reads them as instructions, and verse/chorus are the most reliably respected. A [Breakdown, half-time feel] tag gives you a near-guaranteed rhythm change.

4. Kill the "plastic AI" sound (organic tags)

To make Suno metal sound human, add organic tags and avoid "polished" ones:

Add: raw performance, live room sound, natural pick attack, amp hum, analog distortion
Avoid: studio quality, perfect, polished mix, quantized — these signal "robotic".

5. Exclude what you don't want

In the Style field, prefix tags with a minus to tell Suno what to avoid: deathcore, -pop, -clean vocals, -piano. This stops a piano from crashing your deathcore.

6. The advanced sliders (More Options)

Style Influence: 70–90% — high, so Suno respects your precise tags.
Weirdness: 40–60% — creative but coherent. Higher = chaos.
Audio Influence: 55–75% — when you upload a reference (like a riff WAV), higher sticks closer to it.
