Sponge Music

What is Sponge Music?

Sponge Music is an AI-based Chinese music creation tool owned by ByteDance, provided by Beijing Yanxuan Technology Co., Ltd. Users can input an idea, a piece of lyrics, or other creative material, and the system will then generate the lyrics, melody, arrangement, and singing version.

The product is not designed as a professional digital audio workstation; rather, its purpose is to lower the barriers to creating complete songs. Users without any experience in composition or arrangement can still generate a listenable version of a song first, and then make adjustments to the style, singing method, vocals, and lyrics as needed.

The main functions of Sponge Music

• Enter a theme, a story, or an emotion, and a complete song will be created through inspiration.
• Enter your own lyrics, and the AI will handle the composition, arrangement, and virtual singing.
• With AI-assisted lyric writing, fragmented ideas can be transformed into structured lyrics;
• Upload images or album contents to turn the visual content into songs;
• Add reference music to guide the style and auditory character of the new work;
• Switch between styles, moods, singing techniques, and vocals to create different versions;
• Changing the words, adapting, or replacing the melody of existing works;
• Generate instrumental music for use as an atmospheric soundtrack or background music for videos;
• You can listen to samples, save and share works, and also post them on TikTok.

Inspiration turns into music

Inspiration to Music is designed for users who have only a theme but no lyrics. By entering details such as characters, scenes, stories, emotions, and the desired style, the AI transforms these brief descriptions into lyrics and complete music.

The more specific the instructions are, the more stable the resulting output tends to be. Instead of simply saying “compose a love song,” it’s better to provide details such as the narrative perspective, the historical context, the emotional changes, the musical style, and the way in which it should be sung.

Composing lyrics into songs and AI-generated lyrics

When lyrics are already available, one can use the songwriting function to have the system create the melody, arrangement, and vocals. If only an idea for the lyrics exists, AI can be used to complete the verses, choruses, and other sections first, after which the rhyme, semantics, and narrative coherence can be checked.

Lyrics generated by AI may contain clichés, repetitions, or logical inconsistencies; in particular, character relationships and timelines can become confusing. Before being released officially, the creator should revise each line carefully, ensuring that their own original contributions remain intact.

Image playlists and album playlists

On mobile devices, it is possible to read images selected by the user, turning pictures of trips, anniversaries, pets, or everyday moments into ideas for songs. This feature is useful for creating background music for albums, greeting songs, and content for social media.

Image recognition can only extract limited visual clues and is unable to understand the full narrative behind a particular scene. By providing information about character relationships, locations, emotions, and the message that wants to be conveyed before generating the content, it is possible to reduce mismatches between the lyrics and the photos.

Personalized adaptations and reference music

The current creation interface on the official website offers options such as adding reference music, Music 5.3, and pure music. The mobile version’s specifications also list style, singing method, and voice switching, enabling multiple versions of the same creative idea to be created.

Reference music can help determine the rhythm, instrumentation, and atmosphere, but it should not be used to replicate the voice of a specific living singer or to create an exact copy of a song protected by copyright. Before releasing something, it is necessary to check whether there is any risk of significant similarity in terms of melody, lyrics, and vocals.

Copyright and Commercial Use Notes

AI-generated songs involve various rights related to prompts, lyrics, melodies, arrangement, voice models, and training data. The fact that such songs can be created for free does not automatically mean that they can be used without restrictions in advertisements, for distribution, for sale, or on music platforms.

• For original lyrics, a record of their creation must be kept, while third-party lyrics require permission before use;
• Do not attempt to imitate the voice of a specific singer or replicate the melody of popular songs;
• Reference music is used solely to describe the style, in order to avoid creating a substantial similarity;
• Before using it for commercial purposes, check the latest agreements and the scope of licensing for the works in the account.
• Keep records of manual review when it comes to brands, films, games, or customer projects;
• When releasing to the public, indicate whether it was generated by AI or assisted by AI in accordance with the platform’s rules.

Different judicial jurisdictions may have varying approaches to determining the copyright status of purely AI-generated content, and whether such works are protected also depends on the degree of human creative input. High-value commercial projects should undergo specialized reviews regarding music copyrights and personality rights.

Privacy and Permissions Overview

The official privacy page states that music generation may require the use of the camera, photo album, or microphone once the user grants explicit permission. The Android permissions section also mentions the ability to read images, videos, or files, which is used to import materials for creating music and music videos.
