We ask commercial users to support us in order to help fund the creation and maintenance of these datasets. The MetaBrainz Foundation provides free, open access to various types of useful data gathered and verified by volunteers. Here, we list and describe the various datasets we maintain.
The MusicBrainz Database is built on the PostgreSQL relational database engine and contains all of MusicBrainz' music metadata. This data includes but is not limited to artists, releases, labels and the relationships between them. In addition, there is a full history of all the changes that the MusicBrainz community has made to the data.
MetaBrainz provides full database exports of the MusicBrainz database updated regularly and can be kept in sync with the main MusicBrainz database via the Live Data Feed. The MusicBrainz data dumps can be found on the MusicBrainz FTP Server and more information on the contents of the various dump files can be found in the MusicBrainz documentation.
MetaBrainz also provides access to the music metadata in the MusicBrainz database in the easily consumable format of JSON documents. These JSON dumps can be downloaded from the MusicBrainz FTP Server. These dumps are CC0 licensed but we ask commercial users to support us in order to help fund the creation and maintenance of these datasets.
The ListenBrainz project serves as an archive where users can store their music listening history. This dataset can be used to create new music recommendation engines. The provided data dumps contains over a 100 million listens in the ListenBrainz database. Also provided is access to a live feed of the ListenBrainz data on Google's BigQuery service.
The ListenBrainz project creates new data dumps every two weeks, on the 1st and 15th of every month. These data dumps are CC0 licensed and can be downloaded from the MusicBrainz FTP Server. For more information, please visit the ListenBrainz website and the ListenBrainz data dumps documentation.
The AcousticBrainz project aims to crowdsource acoustic information for all music globally and make it available publicly. This information describes the acoustic characteristics of music, includes low-level spectral information as well as information for genres, moods, keys, scales and much more.
The MetaBrainz Foundation provides dumps of the data in the AcousticBrainz database regularly. These dumps are seperated into low-level and high-level archives, each containing different types of information about music. A download of the full AcousticBrainz database dump is also provided. For more information, please visit the AcousticBrainz downloads page.
CritiqueBrainz is a repository for Creative Commons licensed music reviews. It fills the gap between the factual music metadata in the MusicBrainz database and opinions about music from music critics and listeners by providing a platform that archives Creative Commons licensed reviews.
The MetaBrainz foundation provides full dumps of the CritiqueBrainz database as well as JSON dumps containing reviews in an easily consumable format. These datasets are updated every day and can be downloaded from the MusicBrainz FTP Server.
