Metalheads
Your story, your inside jokes, your worst Monday — turned into a song with real riffs and real screams. One more for the playlist, and nobody else has it.
AI Metal Song Generator
Make a metal song from one sentence — free to start. Tell Lacuna what the song is about and AI writes the verses and chorus, or paste lyrics you wrote yourself. Pick the subgenre, from '80s heavy metal and thrash to metalcore, death, power and nu metal, choose clean vocals, screams or growls, and get a finished track with down-tuned guitars, double-kick drums and a full band.
How it works
Make a metal song with AI in three steps
Step 1
Tell it the story
Under Lyrics, click Inspire and say what the song is about: a war you're fighting at work, a friend far away, the night your band played its first show. AI drafts the verses and chorus; Polish or Extend them until they hit hard. Already wrote the words? Paste them in.
Step 2
Pick the subgenre and the voice
Choose Classic Heavy Metal, Thrash, Metalcore, Death Metal, Power Metal, or Nu Metal, then the voice: clean, gritty, shouted, screamed, growled, or screamed verses with a clean chorus. Open Fine-tune for tempo and up to three parts like a seven-string guitar, a shred solo, or a choir.
Step 3
Keep the best take
Hit Generate and your song is ready in a minute or two; the default model sings two takes to compare. Play them right here, share a link, or open one in the workspace to refine it. Downloads come with paid plans.
What you get
A Metal Song Generator Built for Real Metal
A metal song lives on its riffs and the voice on top of them. Lacuna starts from your words and builds the band around them — from '80s twin-guitar gallops to blast beats and breakdowns.
Lyrics that hit hard
Give the AI metal song generator a story, a grudge, or a name, and it writes verses and a chorus built to be shouted back. Polish the draft, extend it, or rewrite any line yourself before the guitars come in.
Six subgenres, one tap each
Each subgenre sets the riffs, drums, production, tempo, and the usual voice at once: '80s heavy metal with twin leads, thrash at full speed, metalcore breakdowns, death metal blast beats, symphonic power metal, or nu metal groove.
Clean vocals, screams, or growls
Pick how the lyrics are delivered: clean and powerful, gritty, shouted, harsh screams, deep growls, or screamed verses with a soaring clean chorus. The subgenre picks a sensible default; change it to mix things up, like a growled power metal song.
Build the band
Choose up to three parts from seven-string guitar, double-kick drums, shred solo, symphonic orchestra, choir, synths, bass solo, and an acoustic intro, set the tempo from doom-slow to blast beats, and add style notes in your own words.
Your own lyrics, or an instrumental
Paste finished lyrics and Lacuna sings them over the subgenre you pick; switch the model to Lacuna Reverie when every word has to be sung exactly as written. Switch to Instrumental for a backing track to play guitar or drums over.

FAQ
Questions about making metal with AI
An AI metal song generator turns a short idea or your own lyrics into a finished metal song: words, riffs, drums, and a lead vocal. With Lacuna, you pick the subgenre — classic heavy metal, thrash, metalcore, death, power, or nu metal — and the voice, and AI writes, sings, and produces the track.
Click Inspire under Lyrics and describe the song: who or what it's about and how angry, dark, or epic it should feel. Review the lyrics, pick a subgenre and a voice, choose a male or female lead, and hit Generate. Your metal song is ready in a minute or two.
Yes. Under Voice, pick Screamed for harsh metalcore-style screams, Growled for deep death metal growls, or Screams + clean chorus for screamed verses that open into a sung chorus. Harsh vocals are naturally harder to make out than clean singing, so generate two takes and keep the one that sounds right to you.
Yes. Lacuna's metal song maker runs online in your browser and is free to start, with no credit card required. Free credits arrive every month, so you can make and play metal songs at no cost; downloads and commercial use come with paid plans.
It makes the actual song. Many metal lyrics generators stop at words on a page. Lacuna is a complete metal music generator: it writes the lyrics (or takes yours), then sings them over a full band arrangement, so you get a track you can play and share. You can also work on the words first: Inspire, Polish, and Extend edit the lyrics before any music is made.
Six are built in: Classic Heavy Metal ('80s twin-guitar gallop), Thrash, Metalcore, Death Metal, Power Metal (symphonic), and Nu Metal. For anything else, such as doom, black metal, djent, or symphonic metal with a female lead, describe it in the style add-on under Fine-tune.
Yes. Paste your lyrics into Lyrics, pick a subgenre and a voice, and generate. Section tags like [Verse], [Chorus], [Breakdown], and [Guitar Solo] help shape the song, and a note like [Verse - Screamed] or [Chorus - Clean] changes the delivery for that section. To have every word sung exactly as written, switch the model to Lacuna Reverie.
Yes. Switch Vocals to Instrumental and Lacuna produces the arrangement without a singer — a backing track to practice guitar or drums over, to write your own vocals on, or to use under a video.
Yes. Give Inspire the ridiculous version of the story — an inbox from hell, leg day, a cat that knocks everything off the table — pick Death Metal or Thrash, and set the mood to Tongue-in-cheek. Deadly serious riffs under silly lyrics is the whole joke.
Yes, on paid plans. Paid plans include downloads and commercial use under the applicable agreement. Songs created during an active Pro or Ultra subscription also come with a downloadable commercial license agreement; review its terms before you release a song or use it in monetized videos, games, or streams.
