Quick Verdict
Haimian Music, also called Sponge Music, is ByteDance’s Chinese AI music-creation platform. It turns ideas or lyrics into songs and now presents an instrumental mode as well. It is suitable for Chinese song sketches, personal celebration tracks, short-video concepts, and creators who want to hear a musical direction without first learning arranging software.
The product was operational when checked on 2026-07-21, but its canonical URL has changed. The correct official address is https://www.haimian.com. The old directory URL, haimianyue.com, no longer resolved. haimianyinyue.com reached the same service, while the page’s canonical link pointed to haimian.com. This is a domain correction for the same product, not a replacement.
The live homepage showed “Haimian Music Agent,” Music 5.3, Instrumental, Free Creation, Featured Songs, and an Assets entry. Its official description also mentioned song adaptation, lyric creation, and multiple music styles. These signals confirm active operation, but they do not establish that every result can be downloaded, commercially released, sublicensed to clients, or registered as exclusive copyright. Free access, export permission, and output rights are separate questions.
Best For
- Chinese users who want quick pop, Chinese-style, narrative, emotional, or instrumental demos.
- Short-video creators testing an original soundtrack direction before full production.
- Beginners who can describe a story or mood but do not yet use a DAW or understand arrangement.
- Musicians who want alternative lyric and melodic starting points, followed by substantial human revision.
- Teams willing to review lyrics, melodic similarity, synthetic vocals, platform rules, and evidence before release.
- It is not appropriate for adapting an existing song without permission, imitating a real singer, uploading confidential client music, or promising broad customer rights merely because generation is free.
Key Features
- Idea-to-song workflow: users can describe a topic, mood, scene, or story and have the system develop lyrics and music. It is useful for direction-finding rather than proof that a release-ready work is original.
- Lyric creation: the official page description mentions DeepSeek-assisted lyrics and importing lyrics into Haimian. Users remain responsible for the originality and permissions of text they submit.
- Instrumental mode: the current homepage explicitly exposes Instrumental, making the product relevant to background-music sketches as well as vocal songs.
- Current model selector: the public interface displayed Music 5.3. Actual duration, candidate count, voices, variations, and download format should be checked inside the signed-in creation panel.
- Adaptation and assets: official metadata describes adaptation and the site offers asset management. Adapting one’s own song is legally different from adapting another party’s composition or recording.
- Free creation entry: the public call to action currently says Free Creation. If an account later shows points, daily limits, queues, membership, premium exports, or other entitlements, the live account page governs.
Use Cases
- Chinese song drafting: generate a direction, then rewrite lyrics, restructure sections, correct diction, and document human edits. Keep prompt, lyric, generation-date, and revision records.
- Short-video music: check export and use permissions before downloading, then review Douyin, WeChat Channels, Bilibili, or another destination’s rules for synthetic music and rights declarations.
- Personal songs: birthday or memory tracks are lower-risk than advertising or public distribution, but names, voices, and protected lyrics still cannot be used deceptively or without permission.
- Client pitches: use a demo to discuss creative direction. Before final delivery, confirm commercial use, downloads, source-file delivery, customer edits, and redistribution rather than making unsupported license promises.
- Music distribution: review the distributor’s AI policy, disclosure requirements, copyright-eligibility approach, and rules for non-exclusive material before delivering to streaming services or Content ID.
Pricing
On the review date, the official creation button said Free Creation, so the canonical metadata remains pricing: "免费". The public page did not expose a stable paid plan, point bundle, or commercial tier suitable for citation. This guide therefore removes old claims about a fixed daily quota or fixed track duration. Signed-in limits, queues, points, download formats, and premium quality may change and should be verified directly.
Free generation is not exclusive ownership and is not blanket client sublicensing. For a real project, read the user agreement, generation notice, and download screen that apply on the generation date, and retain screenshots. If those terms do not clearly cover advertising, distribution, games, client projects, raw-file delivery, or stock-asset redistribution, request official clarification or use the output only as an internal demo.
Pros
- Direct domestic access with a clear Chinese idea, lyric, and instrumental workflow.
- The live product has progressed to Music 5.3 rather than remaining an old closed-beta page.
- Idea-to-song generation is approachable for users without music-theory or DAW experience.
- Featured songs and asset management help users review results and discover prompt directions.
- The free entry point is useful for testing whether Chinese AI music fits a workflow.
Cons
- The old official domain is dead, so third-party directories and tutorials can send users to the wrong address.
- The public homepage does not state enough about commercial release, client delivery, and standalone distribution rights.
- Free quotas, points, downloads, and premium output may change after login and should not be frozen from old reviews.
- Synthetic singing and melody still need human review for diction, similarity, artifacts, and platform compliance.
- Any future subscription or point purchase would still not clear lyrics, adaptation rights, performer consent, or third-party sources.
Alternatives
| Tool | Best fit | Main advantage | Key tradeoff |
|---|---|---|---|
| Haimian Music | Chinese idea-to-song and instrumental beginners | Domestic access, Chinese workflow, current free entry | Commercial and release rights need same-day verification |
| Suno | Fast complete songs in several languages | Accessible lyrics, vocals, and song structure | Overseas access and plan-specific output rights differ |
| Udio | Users editing and extending songs in sections | More song-oriented iteration controls | Availability and rights policies can change |
| Stable Audio | Instrumental music, loops, and sound effects | SFX, duration control, and training-data disclosure | Vocal songs are not its only focus |
| NetEase Tianyin | Creators wanting a NetEase lyrics-to-demo workflow | Detailed official terms for creation and rights services | Default authorization is non-commercial and external commercial use is restricted |
For scene-based instrumental background music, SOUNDRAW is another option, but its download license cannot be transferred to Haimian output.
FAQ
What is the current official Haimian Music URL?
The canonical URL on the review date was https://www.haimian.com. haimianyinyue.com reached the product but pointed canonically to that address, while the old haimianyue.com no longer resolved.
Is Haimian Music still operating?
Yes. The creation page, Music 5.3 selector, Instrumental mode, featured songs, and asset entry were visible, and no closure notice was found.
Is it completely free?
The public page currently advertises Free Creation, which supports the free classification. Signed-in generation limits, queues, points, downloads, or high-quality output can still change and must be checked in the account.
Can a free song be used commercially?
The words “Free Creation” do not establish a commercial license. Review the applicable agreement and download notice. If advertising, distribution, or client work is not clearly covered, do not market the output as commercially cleared.
May I imitate a singer or adapt someone else’s song?
Not without explicit authorization. Voice, performance, sound-recording, composition, lyric, and adaptation rights are distinct. A product feature does not supply those permissions.
Can I deliver the song to a client for unrestricted reuse?
Only if the live terms and customer agreement support the intended source-file delivery, editing, publication, and redistribution. Personal creation access should not be converted into a promise of perpetual, worldwide, exclusive rights.
What should I check before Content ID registration?
Confirm that the platform accepts AI music and whether disclosure is required. Generated material may be non-exclusive or similar to other results, so do not claim exclusionary Content ID rights without a clear legal and contractual basis.
Bottom Line
Haimian Music remains active, and its canonical address is now haimian.com. Music 5.3, Instrumental, and Free Creation make it a useful Chinese song and demo tool. It should not be presented as an unlimited, copyright-cleared commercial library. Verify export and usage terms on the generation date, obtain lyric, adaptation, and voice permissions, disclose synthetic media when required, and limit customer modification, republication, and Content ID rights in writing.
