HeartMuLa: turn your own lyrics into music locally

Your lyric and tag files, the local and hosted routes, and a same-words style comparison.

The short version

I use this guide to prepare original lyrics and tags, choose a local or hosted test route, and compare style changes without copying a song. HeartMuLa generates music conditioned on lyrics and tags. The recommended 3B checkpoint and code are listed under Apache 2.0; the README distinguishes its released 3B model from an internal 7B Suno comparison.

The source documentation was inspected; I have not independently run the proposed test in this guide. These steps help you choose and check a small first experiment before committing a larger workflow. Any successful output needs its own saved result and configuration.
