AI Song Cover Generator: Your Song, a Different Record
A cover here does not mean copying someone else's hit. You upload a song you own — your own recording, your own demo, a track you have the rights to — and VdoBloom rebuilds it: a new genre over the same melody, an extension that carries the song on from a point you choose, vocals over an instrumental you wrote, or a backing track under a vocal you already have. You describe the new style in a prompt, and the tool does the arranging.
Four actions sit on one form: New style, Add vocals, Add instrumental and Extend. All of them require you to confirm you own the recording or have permission to use it, and the source file can be up to 25 MB and eight minutes long. For a restyle there is a second engine as well, which returns a single version and accepts shorter songs with a longer style description.
What this tool does
- VdoBloom's song cover tool offers four actions on one upload: New style (a restyle into a new genre), Add vocals, Add instrumental and Extend.
- You supply the new style as free text — genre, mood and instruments in the prompt decide how the cover sounds.
- The source song can be up to 25 MB and eight minutes long, and every action requires confirming you own the audio or have permission to use it.
- Restyle has two engines: one returns two versions of the cover, the other returns a single version and accepts songs from six seconds to six minutes with a style description of at least ten characters.
- A cover can keep the original vocal or drop it — there is an Instrumental switch and a vocal gender option for the sung parts.
- New accounts start with free signup credits, one-time credit packs never expire, and subscriptions are also available for a monthly allowance.
What a good restyle prompt looks like
The style prompt is doing two jobs at once: it tells the model what genre to write in, and it tells it which elements of the original to keep. Naming the new palette and the same lead instrument is a strong pattern — "same melody, now a slow soul ballad: rhodes, warm bass, live drums, a horn section answering the vocal" keeps the song recognisable while moving it somewhere new.
If a restyle comes back unrecognisable, the prompt usually overreached: three genres at once, or a request that implies a tempo change so large the melody no longer fits. Anchoring with tempo words — "the same tempo", "slower", "double-time" — is a cheap way to keep the original intact while everything else changes.
Adding vocals, and adding instruments
The two additive actions are the most practical part of the tool. Add instrumental is the one singers reach for: record or upload your own vocal as a bare track and the model writes a backing arrangement under it. Add vocals is the mirror image, for producers with an instrumental and a lyric sheet who need a voice on top — paste the words, name the vocal style, and choose the gender.
Both work best when the source is clean. An instrumental with clip gain already normalised, or a vocal with no reverb tail, gives the model much less to fight through. If you have stems from a previous session, use those rather than a full mix, because the tool does not separate your upload before it generates.
How it works
1.Upload the song and confirm the rights
MP3, WAV or M4A up to 25 MB and eight minutes. You tick the box confirming this is your recording or that you have permission — the tool will not run without it.
2.Pick what should happen
New style for a genre change, Add vocals to sing over your instrumental, Add instrumental to put a backing track under your vocal, or Extend to continue the song from a point you choose.
3.Write the style prompt
For a restyle, describe the new genre in concrete terms — "lofi jazz, soft piano, brushed drums, upright bass" lands far better than "make it different". The longer-description engine needs at least a short sentence.
4.Listen to the whole result
Check that the melody you know is still recognisable and that the new arrangement carries it. Changing one word of the style prompt is usually enough to fix a version that drifted.
Frequently asked questions
Can I cover a song I did not write?
You must own the recording or have permission to use it — the tool asks you to confirm that before it runs, and the provider refuses material that too closely matches an existing commercial recording. Covering a song you did not write is a licensing matter in your jurisdiction and is your responsibility, not something the tool resolves for you.
What happens to my original vocal?
It depends on the action. Add instrumental keeps your vocal and builds a new backing track underneath it. Add vocals goes the other way, singing over your instrumental. On a restyle, the Instrumental switch drops the sung line and returns the arrangement on its own, and there is a vocal gender option when you do want a voice.
How much can the cover change from the original?
The melody and structure are what carry over; the genre, instruments, groove and mix are what change. A folk guitar demo can come back as a lofi jazz piece, an acoustic ballad as an electronic one. What you get back is a version of your song, not a new song, so the source melody is the thing to listen for first.
How long should the song be?
Up to eight minutes and 25 MB fits every action. One restyle engine adds its own limit: it accepts songs from six seconds to six minutes and asks for a style description of at least ten characters, so very long tracks take the other engine instead.
Can I extend a song that ends too early?
Yes — choose Extend and pick the point in the original where the new material should continue from, with the same form controls for style, lyrics and vocal gender. The extension is generated from the end of your source, so the join sounds best when you start it at a bar boundary rather than mid-phrase.
Why was my upload refused?
The most common reason is that the audio matches an existing commercial recording closely enough for the provider to reject it, which is a rights check rather than a fault with your file. Format and size are the other two: use a standard audio file under 25 MB, and make sure the rights box is ticked.
Is it free to try, and do I need a subscription?
New accounts start with free signup credits. After that it runs on credits: one-time packs never expire, and subscriptions exist if you would rather have a monthly allowance. Nothing about the tool is gated behind a plan.
