AI Song Generator: How to Make Songs & What Producers Don’t Tell

👁 117 reads

AI song generators turn text descriptions into complete recordings: vocals, instruments, verses, chorus. Not just a backing track or loop, but a full song. We made dozens of them, including three songs in Polish across different genres, and below we share what you won’t find in the producers’ descriptions.

How AI Song Generators Work

You provide two things: a style description and song lyrics. You can write the lyrics yourself or let the tool write them. You get an audio file, usually with two variants to choose from.

All the quality is determined by the style description, not the lyrics. This is the most common beginner mistake: spending an hour perfecting the words and three words in the style field.

Four Things We Learned From Our Own Generations

The model rewrites your prompt. What you type doesn’t reach the generator literally. It gets rewritten, and you only see the version after rewriting. That’s why two similar descriptions can produce completely different results, and why copying other people’s prompts works worse than it seems.

Specify language in the style description, not just in lyrics. Writing the target language (e.g. “Polish vocal”) in the style field improves pronunciation much more clearly than non-English lyrics alone. Without it, the model can sing non-English words with an English accent.

Specify tempo with numbers. “142 BPM” works. “Fast” means nothing and the model will do whatever it wants.

Order in the description matters. The beginning of the description is treated more seriously than the end. Genre and language up front, mixing details at the end.

How Much It Costs and What’s Free

All major generators work on the same principle: you get a pool to use up, because each generation costs real money on the provider’s side. “Free” here means “no payment, in exchange for a limit,” not “unlimited.”

A concrete fact worth knowing: in Suno’s latest generation, the lightest model, v6-mini, is available to everyone, including free accounts. The producer claims it delivers better and faster results than any free model on any music platform, though this is a statement without measurements provided, so we treat it as a claim to verify.

Practical takeaway: the free pool is enough to check whether the tool does what you expect at all. It’s not enough for regular work. If you plan to do this weekly, factor in the cost right away.

What Not to Expect

Songs come out short. You won’t get a four-minute piece with elaborate structure, just a concise track. For video background music this is an advantage, for listening it’s a drawback.

Non-English vocals can be uneven. With words that have difficult pronunciation, you can hear it’s synthesis. This improves with each version, but it’s not yet at an indistinguishable level. We tested it in Polish, a useful proxy for heavily inflected languages.

Repeatability is limited. The same description, run twice, will produce two different songs. For commissioned work this is a problem, because it’s hard to explain to a client that the approved version can’t be reproduced.

Rights to AI-Generated Songs

This is the most frequently asked question, and the answer isn’t simple. Terms of use depend on the platform and whether you have a paid plan, so you need to read them for the specific tool, not assume.

The legal context around generated music is in flux. On one hand, Warner Music Group, BMG and Believe signed on with Suno, which is the first situation where a generator launches a new version together with labels. On the other hand, a German court ruled against Suno in a copyright infringement case. Before you release such a track commercially, check the current state, because it changes every few months.

Where to Start With AI Song Generators

The shortest path: take a specific genre, specify tempo with a number, add language in the style description, and write your own lyrics instead of leaving them to the tool. Four things that make most of the difference.

A ready-made style description template, broken down into six elements, with a list of mistakes that cost us the most generations, we collected in a guide on writing prompts. If you prefer to see the result before installing anything, in the article about three Polish tracks there are full prompts and finished recordings to listen to: rap, K-pop and electropop, all in Polish. We described the basics of the tool itself in the article about Suno AI, and what the latest generation of models changed in the article about Suno v6.
