AI Music Remix

Problem It Solves

AI Music Remix is for creators who already have usable audio material and need fast derivative versions. The task is not usually “write a song from scratch,” but “keep the groove, melody, and mood of a demo or reference track, then change the style, arrangement, or chorus direction.” It also fits extending an existing song into versions for short videos or commercial content.

The result is a new, playable, downloadable version. Works sync to the Sponge Music account and can be managed in the Sponge Music AI Song mini program or on lexuan.club.

How It Works

The main entry point is a local Node CLI, with aimv as the recommended Agent tool name. If the Agent can run shell commands, it should handle initialization, generation, querying, and downloading directly, instead of asking the user to copy commands or open a web page.

Key steps:
- Provide a demo, reference audio, existing song, or project ID;
- Describe what to keep: groove, melody, mood;
- Describe what to change: style, arrangement, chorus direction;
- Generate candidate versions and preview them;
- Download or query the project based on status.

The CLI returns structured [error] / [hint] labels. For example, missing authentication returns a connect_url; insufficient credits or quota returns a pay_url; timeout means the task may still be running. In sandboxed environments where only curl is available, the CLI can fall back to system curl transport.

Boundaries and Notes

This skill is closer to audio-conditioned remixing than text-only songwriting. If the reference material is not ready, the project ID is invalid, or account quota is insufficient, generation may not succeed immediately. wait_timeout does not mean failure, while reference_not_ready means the material status should be checked first.

Also, bin/aimv.js is a local CLI and should not be registered as an MCP stdio service. Account, credits, membership, and the work library are shared with the Sponge Music ecosystem.
