OpusTag

OpusTag is a modern, elegant audio metadata manager designed specifically for classical music collectors. It combines a powerful local library organizer with an integrated high-resolution cover art fetcher powered by the iTunes API.

✨ Features

• Apple Music-Inspired UI: A clean, dark-mode interface with frosted glass effects and fluid animations.
• High-Res Cover Art: Search and download original artwork (up to 3000px+) directly from Apple's servers.
• One-Click Embedding: Automatically match and embed cover art into your FLAC files.
• Metadata Editing: Edit album titles, artists, years, genres, and composers with a streamlined bulk editor.
• Local Library: Scan your local music folder and visualize your collection in a beautiful grid.
• Dockerized: Fully containerized for easy deployment and isolation.

🚀 Getting Started

OpusTag can be installed as a Python package or run via Docker.

Prerequisites

• A folder containing your music collection.

Installation (Pip)

This will launch the server and open your default web browser to the OpusTag interface.

Pull and run the pre-built image from Docker Hub:

docker run -d \
  -p 8000:8000 \
  -v /path/to/your/music:/music \

📖 Usage Guide

1. Searching for Artwork

• Go to the Search tab (default view).
• Type an artist, album, or composer name (e.g., "Karajan Beethoven 9").
• Browse high-resolution results from Apple Music.
• Click the Search Icon to view the full-size original image in a new tab.
• Click the Download Icon to save the image locally.

2. Managing Your Library

• Switch to the Library tab via the sidebar.
• Click the Refresh button to scan your mapped music folder.
• Your albums will appear in a grid. Albums missing covers will show a placeholder disc icon.

3. Editing & Embedding

• Click on any album to open the Detail View.
• Add/Replace Cover: Click "Auto-Match / Replace Cover". A search window will appear pre-filled with the album's info. Select the correct cover, and OpusTag will automatically download and embed it into all tracks of that album.
