This AI music generator comparison tests five different approaches to music creation: complete AI songs, prompt-based instrumental music, licensed background music, and creator-focused audio workflows. The original video compared Suno, Udio, MusicFX, Rightsify/Hydra, and Loudly. Their plans and features have changed, so “free” should be read as a current entry option to verify—not a permanent promise.
Watch the original five-tool AI music generator test on YouTube, then use the updated framework below to compare the tools with the same prompt and licensing requirements.
The five AI music tools in the tutorial
1. Suno
Suno creates complete songs from a simple prompt or user-supplied lyrics and now includes more granular editing and production controls. Its current site advertises a daily free creation allowance, while commercial rights are tied to eligible paid output and current terms. Check the plan that applies when the song is generated rather than upgrading after the fact and assuming earlier tracks changed status.
2. Udio
Udio is another full-song generation and editing platform. It is useful for comparing vocals, song structure, prompt interpretation, and iterative editing. Its plan, download options, and rights can change, so review the current pricing and terms before using a track in monetized content or distribution.
3. Google MusicFX
MusicFX is Google’s experimental prompt-to-music experience. It is better suited to musical ideas, textures, and instrumental exploration than assuming a finished commercial song workflow. Availability may depend on region and product rollout. Check the current Google Labs interface and permitted use before building a production process around it.
4. Rightsify and Hydra
Rightsify should not be treated as a direct substitute for a consumer vocal-song generator. It is a music-licensing platform, and Hydra is its generative music technology. This option is more relevant when the priority is background music and licensing for commercial environments or content, rather than creating a conventional singer-led track.
5. Loudly
Loudly positions itself as a rights-safe AI music platform for creators, artists, and brands. Its current workflow includes multiple generation models, instrumental and vocal options, remixing, mastering, stem splitting, and distribution. Confirm which model and plan govern the output you intend to publish.

How to compare AI music generators fairly
Use the same creative brief
A fair test uses the same musical goal, not necessarily identical wording when the tools expose different controls. Write a brief with:
- Genre and subgenre
- Mood and energy
- Tempo range
- Main instruments
- Vocal or instrumental requirement
- Song subject or lyric theme
- Approximate structure and duration
- Intended use, such as background music or a full song
Example: “Upbeat synth-pop track about starting over, bright female vocal, 118 BPM, punchy drums, warm analog synths, short intro, strong eight-line chorus, clean modern production.” Do not ask for the voice or exact style of a living artist.
Generate the same number of attempts
Give each platform the same opportunity. For example, create two or three results, select the strongest one, and record how many credits and minutes the process required. Comparing one lucky output with another tool’s first failure produces a misleading conclusion.
Score the complete workflow
| Criterion | What to listen for or verify |
|---|---|
| Prompt accuracy | Genre, mood, instrumentation, and subject match |
| Composition | Memorable structure, transitions, and musical development |
| Vocal quality | Pronunciation, emotion, artifacts, and intelligibility |
| Audio quality | Clipping, noise, harshness, stereo balance, and dynamics |
| Editing control | Lyrics, sections, extension, stems, remixing, and regeneration |
| Cost | Credits required for an acceptable result |
| Rights | Commercial use, attribution, distribution, and plan conditions |
| Privacy | Treatment of uploaded lyrics, vocals, and audio |
Free does not automatically mean commercial
A free plan may allow experimentation while restricting monetization, client work, distribution, downloads, or ownership claims. Save the terms and plan details that applied on the generation date. If you upgrade later, do not assume that output created under the free plan automatically receives the paid plan’s license.
Also distinguish between a platform license and copyright law. A service can grant permission under its terms, but the legal protection available for largely AI-generated music can differ by jurisdiction and level of human authorship.
How to improve an AI-generated song
- Rewrite weak lyrics in your own words.
- Regenerate only the failed section when the editor allows it.
- Export stems and rebalance vocals, drums, bass, and instruments.
- Correct the structure in a DAW rather than accepting a repetitive arrangement.
- Add your own performance, sound design, or instrumental layer.
- Master the track for the destination platform without crushing its dynamics.
- Keep prompts, versions, source files, licenses, and contributor records.
Which tool should you choose?
- Choose a full-song generator when you need vocals, lyrics, and complete song structure.
- Choose an instrumental generator when narration or visuals need unobtrusive background music.
- Choose a licensing-focused platform when rights documentation is the main requirement.
- Choose a tool with stems and editing controls when you plan to finish the track professionally.
- Choose based on the final acceptable result and license, not the most impressive marketing demo.

Conclusion
The best AI music generator depends on whether you need a complete song, instrumental bed, editable stems, or rights-focused production. Test the same brief, count the real cost of acceptable output, and read the license before publishing. The video provides the listening comparison; this updated checklist helps you make a defensible production decision.
