MusicBrainz Data Parser

This script processes and harmonizes the MusicBrainz release.tar.xz data dump. It extracts essential release information, including:

• Release titles and dates
• Artist names
• Track listings with durations
• Genres and subgenres (from tags)
• Labels and country of release

The script handles large datasets efficiently using multiprocessing and logs critical errors for review.

Usage

Ensure you have the required dependencies installed:

pip install ujson tqdm

Run the script with:

python prepare20M.py --tar-file path/to/release.tar.xz --output-dir output_directory

Replace path/to/release.tar.xz with the path to your MusicBrainz data file and output_directory with your desired output folder.

Output

• Processed JSON files containing essential release data.
• A log file mb_processing_errors.log capturing critical errors.
• A rejected_records folder with samples of records that were not processed.
