Created by: Lester Caine, Last modification: 22 Feb 2025 (08:24 UTC)

The Compact Disc Database (CDDB) is a database of audio CD information, including track listings, which was used by various media player software to retrieve information about CDs. The history of CDDB and its sources has evolved significantly over time. Here is a summary of its key milestones and sources as built by Mistral AI with a little prompting:

  1. Early Development (1990s):
    Grateful Dead: The initial concept for CDDB was inspired by the need to catalog the extensive collection of live recordings by the Grateful Dead. Fans of the band created a database to share information about their CDs. ◦ Freedb: In 1998, CDDB was forked into Freedb, an open-source alternative that aimed to provide a free and community-driven database. Freedb allowed users to submit and retrieve CD information without the need for a centralized authority.
  2. Gracenote (Late 1990s - Present):
    Acquisition: In 2002, CDDB was acquired by Gracenote, a company that specializes in music recognition and metadata services. Gracenote continued to operate the database and expanded its services to include music recognition technology.
    MusicID: Gracenote's MusicID technology allows users to identify songs and albums by analyzing audio fingerprints. This technology is used in various media players, smartphones, and other devices to provide metadata for music files.
    Integration with Services: Gracenote's database is integrated with numerous music streaming services, media players, and automotive systems, providing a comprehensive source of music metadata.
  3. Community Contributions:
    User Submissions: Both CDDB and Freedb relied heavily on user submissions to build and maintain their databases. Users could submit track listings, album information, and other metadata, which were then reviewed and added to the database.
    Open Source: Freedb, being open-source, allowed developers to contribute to its development and improvement. This community-driven approach helped to keep the database up-to-date and comprehensive.
  4. Transition to Digital Services:
    Online Databases: With the rise of digital music services, CDDB and Freedb transitioned from being primarily CD-focused to including digital music files. This shift allowed users to retrieve metadata for MP3s, FLACs, and other digital audio formats.
    APIs and SDKs: Gracenote provides APIs and SDKs that developers can use to integrate music recognition and metadata services into their applications. This has helped to expand the reach and utility of the database.
  5. GNUdb.org (Present):
    Freedb Data Storage: Today, the data from Freedb is stored and maintained at gnudb.org. This site continues the open-source tradition of Freedb, allowing users to submit and retrieve CD information freely.
    Community-Driven: GNUdb.org is community-driven, relying on user contributions to keep the database up-to-date. It provides a platform for users to share and access CD metadata, ensuring that the database remains comprehensive and accurate.
  6. MusicBrainz (Present):
    Open Music Encyclopedia: MusicBrainz is an open music encyclopedia that provides a free and open database of music information. It is community-driven and offers a comprehensive set of tools for music identification and metadata management.
    Popularity: MusicBrainz is widely used by music enthusiasts, developers, and various applications due to its open nature and extensive metadata. It supports a wide range of audio formats and provides detailed information about artists, albums, and tracks.
    Integration: MusicBrainz is integrated with many music players, libraries, and services, making it a popular choice for users who prefer open-source solutions.
  7. Discogs (Present):
    Comprehensive Database: Discogs is a crowdsourced online database of music information, including releases, artists, and labels. It is known for its extensive coverage of various music genres, including rare and obscure releases.
    Community-Driven: Discogs relies on user contributions to build and maintain its database. Users can submit information about releases, which are then reviewed and added to the database.
    Popularity: Discogs is popular among music collectors, enthusiasts, and professionals due to its comprehensive and detailed information. It is often used as a reference for music metadata and is integrated with various music services and applications.
  8. Current Status:
    Gracenote: Gracenote remains a significant provider of music metadata services, offering a vast database of music information used by a wide range of applications and services. Its MusicID technology is particularly notable for its audio fingerprinting capabilities, which allow for accurate music identification.
    MusicBrainz and Discogs: These platforms have gained significant popularity and are widely used by music enthusiasts, developers, and various applications. MusicBrainz is appreciated for its open-source nature and comprehensive metadata, while Discogs is valued for its extensive coverage of music releases, including rare and obscure titles. Both platforms are community-driven and rely on user contributions to maintain and expand their databases.
    Integration and Use Cases: Gracenote, MusicBrainz, and Discogs are integrated into various music players, streaming services, and other applications. Users often choose between these services based on their specific needs, such as the desire for open-source solutions, comprehensive metadata, or extensive coverage of music releases.

In summary, the landscape of music metadata sources has evolved to include both commercial services like Gracenote and community-driven platforms like MusicBrainz and Discogs. Each of these sources has its strengths and is used by different segments of the music community, contributing to a rich and diverse ecosystem of music information.

I find this summary a little biased towards using the commercial service still despite trying to push the open source pathway. I will have another go at padding out the differences between the two different database bases. Just which players are using which is something that can be a bit woolly and result in differences in the information provided. Storing my preferred versions locally is a lot easier now I have MusicBrainz Picard metadata editor working.
