README Excerpt

TagMend cleans up the **genre** and **artist-name** tags in your music library using **Last.fm**, and fills in album original-release years from **MusicBrainz**. Every change is staged first and committed as a revertible unit, so nothing touches your files until you say so, and any change can be rolled back. It ships as both a command-line tool and an MCP server, so you can drive it yourself or hand it to an AI assistant like Claude. Built to make [Navidrome MCP](https://github.com/Blakeem/Navid
