==Purpose==

This page lists some very general [[Frequently Asked Questions|FrequentlyAskedQuestions]] about MusicBrainz and how to use the site. There are also [[Frequently Asked Questions|FrequentlyAskedQuestions]] specific to different subjects.

If that still doesn't help, please find us in one of the [[MusicBrainz Forum|MusicBrainzForum]]<code><nowiki></nowiki></code>s or via the [http://www.musicbrainz.org/support/contact.html contact page].

====What's the purpose of this site?====
===What's the purpose of MusicBrainz?===
This site is intended to be a free, on-line encyclopedia of music information. We (and you, if you decide to join us) are building an open-source database containing all the information you would ever want to know about songs, releases, and artists.


===Why would I need to use MusicBrainz? What's wrong with Gracenote's CDDB?===
This site is intended to be a free, on-line encyclopedia of music information. We (and you, if you decide to join us) are building an open-source database containing all the information you would ever want to know about songs, albums, and artists.
No one needs to use our site, and nothing is wrong with CDDB. We just have a different aim from the maintainers of CDDB. Check the [[About/History|history page]] for more information on the origins of this project.

This site is free. CDDB is not.


CDDB was made by volunteers sharing the track listings of their CDs with the central server that was run voluntarily, not for profit. This freely volunteered effort was effectively stolen by Gracenote, who made it a commercial service that you have to pay to use in your music player software, or if you want to download large parts of the database for whatever reason.

===Why would I need to use MusicBrainz? What's wrong with FreeDB?===
No one needs to use our site, and nothing's wrong with CDDB. We just have a different aim from the maintainers of CDDB. Check the history pages for more information on the origins of this project.
It no longer exists, Magix took the service on freedb.org down in 2020.


===Why would I need to use MusicBrainz? What's wrong with GnuDB?===
This site is free. CDDB is not.
Gnudb.org is the new home of [[FreeDB]] which is based on the last version of CDDB that was freely available. While it is a very useful site, it is technically inferior to this site as it is based on a flat format. i.e. releases are not grouped by artists, they just have a text field "Artist Name". Different printings of the same release that are not quite identical go into the listing twice etc. There is no concept of a single track being on more than one release -- a track doesn't really exist in its own right. While MusicBrainz is not perfect in this respect, it is a lot better, and plans for improvements are laid down. The path to achieving those goals is clear. It would be very hard to give FreeDB those facilities. Eventually it is envisioned by some that MusicBrainz could take over from FreeDB, although they may evolve to take different markets, or be competitors continually spurring each other on.


The feature to import [[medium]]s manually from FreeDB was removed in January 2017 [https://tickets.metabrainz.org/browse/MBS-9143]

[[FreeDB]] is based on the last version of CDDB that was freely available. While it is a very useful site, it is technically inferior to this site as it is based on a flat format. Ie. Albums are not grouped by artists, they just have a text field "Artist Name". Different printings of the same album that are not quite identical go into the listing twice etc. There is no concept of a single track being on more than one album - a track doesn't really exist in its own right. While [[MusicBrainz]] is not perfect in this respect, it is a lot better, and plans for improvements are laid down. The path to acheiving those goals is clear. It would be very hard to give [[FreeDB]] those facilities. Eventually it is envisioned by some that [[MusicBrainz]] could take over from [[FreeDB]], although they may evolve to take different markets, or be competitors continually spurring each other on.

This page answers Frequently Asked Questions about MusicBrainz.

If this page doesn't answer your question, please ask it in the MetaBrainz Forum or contact us. If you would like to update this page on the wiki, feel free to do so but please do not add questions without answers.

General Questions

What's the purpose of MusicBrainz?

This site is intended to be a free, on-line encyclopedia of music information. We (and you, if you decide to join us) are building an open-source database containing all the information you would ever want to know about songs, releases, and artists.

Why would I need to use MusicBrainz? What's wrong with Gracenote's CDDB?

No one needs to use our site, and nothing is wrong with CDDB. We just have a different aim from the maintainers of CDDB. Check the history page for more information on the origins of this project.

This site is free. CDDB is not.

CDDB was made by volunteers sharing the track listings of their CDs with the central server that was run voluntarily, not for profit. This freely volunteered effort was effectively stolen by Gracenote, who made it a commercial service that you have to pay to use in your music player software, or if you want to download large parts of the database for whatever reason.

Why would I need to use MusicBrainz? What's wrong with FreeDB?

It no longer exists, Magix took the service on freedb.org down in 2020.

Why would I need to use MusicBrainz? What's wrong with GnuDB?

Gnudb.org is the new home of FreeDB which is based on the last version of CDDB that was freely available. While it is a very useful site, it is technically inferior to this site as it is based on a flat format. i.e. releases are not grouped by artists, they just have a text field "Artist Name". Different printings of the same release that are not quite identical go into the listing twice etc. There is no concept of a single track being on more than one release -- a track doesn't really exist in its own right. While MusicBrainz is not perfect in this respect, it is a lot better, and plans for improvements are laid down. The path to achieving those goals is clear. It would be very hard to give FreeDB those facilities. Eventually it is envisioned by some that MusicBrainz could take over from FreeDB, although they may evolve to take different markets, or be competitors continually spurring each other on.

The feature to import mediums manually from FreeDB was removed in January 2017 [1]

Is there a mailing list for MusicBrainz?
