Beatoria: 10,381 AI Cover Songs That Reimagine Famous Tracks With Completely New Lyrics

Beatoria is a free catalogue of AI cover songs built on an unusual rule: every track re-sings a famous song in a new voice, but not one line of the original lyrics is reproduced. Ten thousand tracks, twenty-five vocal languages, fourteen genres, nearly eight thousand style prompts — and a studio where you can generate your own. Here is how the whole thing is put together.

The Idea in One Sentence

Take a song everybody knows. Keep the feeling of it — the genre, the era, the energy, the shape of the arrangement. Then write entirely new lyrics for it, generate a new vocal, credit the original openly, and publish the result under an invented artist name.

That is Beatoria. It is not a karaoke site, not a stem-splitter, not a voice-clone tool, and not a lyric archive. It is a catalogue of original songs that are in conversation with famous ones — and the distinction between those two things is the entire product.

So a track sits in the catalogue as "Snow From Another Year" — a cover of White Christmas — Bing Crosby. Or "Flicker in the Draft", a cover of Candle in the Wind 1997 — Elton John. Or "Цвіт опівночі", reaching back to Червона рута — Володимир Івасюк. The attribution is on the page; the words are new.

The Catalogue, By the Numbers

Genres

Fourteen buckets, and the distribution is a fair picture of what popular music actually is:

Languages

Twenty-five vocal languages, and this is where the catalogue stops looking like an English-language novelty project. English leads with 4,122 tracks, but Spanish holds 1,105, Hindi 592, Korean 488, Japanese 431, Portuguese 422, Chinese 382, French 304, Turkish 237, Arabic 230, Russian 229, Italian 228, German 220, Ukrainian 200, Swedish 171 — and then a long, deliberately even tail of 115 tracks each in Indonesian, Persian, Polish, Vietnamese, Hebrew, Thai, Greek and Tagalog, plus 76 in Dutch.

That flat tail is not an accident of the data. It is a production decision: a fixed batch was generated per language so that a listener arriving from Manila, Tehran or Bangkok finds a real section rather than three tokens.

Countries

Thirty-two countries have their own browsable section — United Kingdom, Spain, India, South Korea, Japan, Portugal, Ukraine, China, France, Turkey, Egypt, Italy, Russia, Germany, Sweden, Vietnam, Israel, Philippines, Iran, Indonesia, Thailand, Greece, Poland, Netherlands, Uzbekistan, Bangladesh, USA and more. Country is a separate axis from language, because a Bollywood track and a Hindi-language track are not the same query.

Artists and albums

3,219 original artists are referenced across the catalogue, and 186 albums group tracks into curated collections. Each referenced artist gets a pseudonym — the invented performer name the AI covers are published under. The Beatles' covers appear as Ash Titan; Elvis Presley's as Saint & the Beacons; Aretha Franklin's as The Northern Crowns; Marvin Gaye's as Iron Circuits. It is a small design decision that does a lot of work: it keeps the credit honest while making it unmistakable that you are not listening to the original performer.

How You Browse Ten Thousand Songs

A catalogue this size is only as good as the ways into it, and Beatoria exposes five independent axes, each with its own set of pages:

That prompt list is worth dwelling on. Seven thousand eight hundred and eighty-two distinct style descriptions, ranging from the broad (trap, disco rock, uptempo pop, dance pop EDM) to the wonderfully specific (1975 super robot anime theme, mid 2000s Spanish pop rock, tulip-themed, robotic vocoder, festive patriotic, galloping riff, brass hook, female harmony). Each is a page, and each page is a way in.

The Facet System Underneath

Behind the visible taxonomy sits a second, structured one: 55 facets across seven orthogonal groups, attached to tracks and used for filtering and for the site's "more like this" logic.

The interesting part is how these are weighted when sorting. The catalogue's relevance ranking does not treat all facet matches equally — narrow, meaningful facets (era, mood, activity) count for more than broad ones (tempo, energy), because everything is some tempo but only some things are nostalgic 80s driving music. Popularity, measured from real play counts, is the tie-breaker.

That combination — activity plus mood plus era — is quietly the most useful thing in the interface. "Something epic for a workout that sounds like the eighties" is a real query here, not a marketing example.

The Create Studio

Browsing is open to everyone with no account. Generating is where you sign in — and the flow is built so that nothing you make touches the public catalogue until you decide it should.

What you control

• Caption / prompt A free-text description of the song you want — genre, mood, instrumentation, era, anything. This is the primary steering wheel.
• Lyrics Your own words, or generated ones. Either way they are the text the model sings.
• Vocal language Any of the twenty-five languages the catalogue supports.
• Duration Set per track; the catalogue's own tracks mostly run 150–180 seconds.
• Variants Up to four takes generated from a single request, so you can pick rather than re-roll.
• Reference audio Optional. Drop in a track and the system uses it as a cover reference.

The reference-audio trick

This is the cleverest small feature in the product. Upload a reference track and, before anything is generated, the file goes through a lightweight librosa-based analysis — no machine learning, just signal analysis — which reads the musical shape of the audio and auto-fills the prompt field with a style description derived from it.

So instead of staring at an empty text box trying to describe a sound in words, you hand the system the sound and it writes the first draft of the description for you. You then edit that description, which is a far easier task than authoring it cold.

The analysis is stateless — the upload is written to a temporary file, analysed, and deleted. Nothing is retained.

Staging, then publishing

Everything you generate lands in a private staging area scoped to your account, in a separate set of tables and a separate output folder from the public catalogue. From there you have exactly three options, all of which are yours alone to take:

1. Publish a chosen take into the public catalogue, where it becomes a normal catalogue entry with its taxonomy attached;
2. Delete a single take you do not want, leaving the rest of the batch;
3. Delete the whole job, and everything in it.

There is a parallel, admin-only version of the same machinery for regenerating existing catalogue tracks — generate up to four new takes for an existing song, then either replace the original in place or publish the take as a brand-new entry. Same separation, same explicit-action rule: nothing reaches the public catalogue automatically.

What Is Actually Generating the Music

Beatoria runs on ACE-Step, an open music-generation model, driven through a Gradio API on a dedicated GPU box rather than through a third-party music API. That choice has consequences worth spelling out, because they are visible in the product.

• No per-track API bill The engine is a machine the project rents, not a service it meters. Ten thousand tracks exist because generating the ten-thousandth one cost nothing beyond the hours already paid for.
• Direct parameter control The web app talks to the engine's generation call directly, setting the caption, lyrics, language, duration and variant count as explicit arguments rather than through a simplified vendor wrapper.
• A dedicated cover path Reference-audio covers need a session that survives across calls, so they go through a Python bridge using the Gradio client rather than plain HTTP. It is a small piece of engineering that exists purely because the naive approach loses state between the upload and the generate.
• A deliberate softness The cover mode is tuned to regenerate the vocal for the new lyrics rather than clone the reference exactly. The resemblance comes from the caption, the style, the tempo and the lyric shape — not from copying a performance.

That last point is not a technical limitation; it is the product's ethics implemented in a parameter. A system tuned for maximum resemblance would produce something closer to an impersonation. Beatoria's is tuned to produce something closer to a new recording that remembers an old one.

The Listening Layer

The site tracks playback in more detail than a simple play counter, and it does so per track rather than per page view:

The threshold counters are the honest ones. In generated music the gap between started and survived fifteen seconds is enormous, and tracking it separately is what lets the catalogue's popularity sorting mean something. A track with a thousand starts and forty completions is not a hit; a track with two hundred starts and a hundred and sixty completions is.

On top of that sit playlists, per-user download history, votes, and an account layer with both local email/password sign-in and Google OAuth. Listening never requires any of it — the auth exists to unlock creation, playlists and history, not to gate the catalogue.

Built as a Real Application, Not a Wrapper

The stack is worth a paragraph because it explains why a ten-thousand-track catalogue loads the way it does.

The front end is a Vue single-page application with server-side prerendering, split into per-route bundles — Home, Library, Category, Song, Artist, Artists, Album, Albums, Country, Countries, Promt, Promts, Create, Account, Guide, Info. The backend is a PHP 8.3 API with a clean class-per-domain layout (Catalog, Song, Artists, Albums, Countries, Prompts, Jobs, Creates, Renders, Analyze, Playlist, Listens, Downloads, Votes, Auth, GoogleOAuth) behind a single router.

Three details show the level of care:

• Per-page SEO metadata lives in the database, not in the JavaScript bundle. The prerender build reads it so every route ships a correct, unique title and description in the HTML — a single-page app that is genuinely indexable rather than nominally so.
• Fonts are self-hosted, with the above-the-fold faces preloaded. This kills a render-blocking third-party request and the late font-swap layout shift that comes with it.
• Search queries and intent terms are logged, so what people actually look for feeds back into how the catalogue is organised.

There is also a machine-readable llms.txt at the root, written specifically for AI answer engines. It states what the site is, lists the key pages, and — pointedly — states the lyrics rule in a form a model can quote. Given that the catalogue's entire legal footing rests on that distinction, publishing it where the answer engines will read it is exactly the right move.

The API Behind the Site

Beatoria's front end is a client of its own public JSON API, which means everything the site can do is reachable programmatically. The router exposes one segment per domain:

A single catalogue call returns the total, the page, the per-page size, the page count, the full genre list, the live facet counts for every genre, and the items themselves — each with its tracks, variants, poster art, language, duration, cover attribution and play count. It is a complete browse surface in one request, which is why the SPA feels the way it does.

Where Beatoria Sits in the AI-Music Landscape

The AI music space has sorted itself into four rough categories, and Beatoria is deliberately in the one with the fewest occupants.

The practical difference is what happens in the first ten seconds. On a generator you get an empty prompt box. On Beatoria you get a library. Most people, most of the time, want the library — and the generator is there for the minority of visits where they do not.

The second difference is the licensing story. A track whose lyrics were written for it and whose audio was produced by a model the project runs itself has a far simpler rights profile than a voice conversion of a commercial recording. That is not a legal opinion, and it is not a licence — but it is the reason the catalogue can exist at this scale and be free to listen to.

The Lyrics Question, Answered Directly

Any project that puts the word "cover" next to famous song titles invites an obvious question, so it is worth answering it plainly rather than burying it.

The Honest Bits

• It is a catalogue first The overwhelming majority of the ten thousand tracks were produced in batch by the project itself, not by users. The Create studio is real and open, but the library is the product.
• AI vocals are still AI vocals ACE-Step is a strong open model and it is not a session singer. Some genres — big ballads, orchestral, close-harmony work — hold up notably better than others.
• The prompts show their seams Nearly eight thousand style prompts written across a production run means some of them are wonderfully precise and some are three words long. They are browsable anyway, which is arguably the honest choice.
• Covers are references, not reproductions If you arrive expecting to hear the actual melody of a famous song with new words on top, that is not what this is. The relationship to the original is genre, era, mood and shape — plus an open credit.

Who It Is Actually For

• Listeners who want background music with a shape Ten thousand tracks filtered by activity, mood and era, free, no account, no ads in the way of playback.
• Creators who need original music they can use Tracks with original lyrics and no sampled recording behind them are a very different licensing conversation from a commercial song.
• People learning to prompt music models Seven thousand style prompts, each attached to the track it produced, is one of the better public corpora of "this prompt made this sound" that exists.
• Non-English listeners Twenty-five vocal languages with real volume behind each of them, and country sections separate from language sections.
• Anyone who wants to make one Sign in, describe a song or drop a reference track, get four takes, keep the one you like — and it stays private unless you publish it.

The Short Version

Beatoria is 10,381 AI-generated songs — 10,367 of them covers in the specific sense the site defines: a famous track reimagined with completely new, original lyrics, sung by an AI voice, published under an invented artist name, with the original credited by name and artist. Fourteen genres, twenty-five vocal languages, thirty-two country sections, 3,219 referenced artists, 186 albums and 7,882 browsable style prompts, all free to listen to with no account.

Behind it sits a self-hosted ACE-Step engine, a facet system of 55 tags across seven groups, real listening analytics down to threshold completion rates, and a create-your-own studio where four takes arrive per request, a reference upload writes your prompt for you, and nothing becomes public until you press publish.

Every lyric on Beatoria is original text written for that track. They do not reproduce the copyrighted lyrics of the original songs.
