The data collected by the MusicBrainz project falls into two categories explained below. Any user that contributes to MusicBrainz should be aware that their contributions will be made available to the public under the licenses described below. Furthermore, MusicBrainz users give the MetaBrainz Foundation the right to license this data for commercial use. The income from these licenses keeps MusicBrainz running and covers the paychecks of paid MusicBrainz developers.
Public Domain Data
The core data of the MusicBrainz dataset is placed into the Public Domain, which means that anyone can download and use the core data in any way they see fit. No restictions, no worries! The core data consists of the following pieces of data. The SQL tablenames are shown in parentheses after the description of the data:
- Artists and Artist Aliases (
- Release Groups (
- Releases (
- Tracks (
- Labels and Label Aliases (
- Disc IDs (CD Identification) information (
- ISRCs (recordings identifiers) (
- PUIDs Identifiers and related data (
- Release Events (
- Advanced Relationships (
- CD Stubs (
The live data feed that we offer to replicate the MusicBrainz data is a slight exception to the rules above, since both Public Domain data and Creative Commons data (see below) are intermingled in the data update packets. Given that the highest common license denominator needs to be applied to these data packets, the Creative Commons license governs the live data-feeds.

Creative Commons Licensed Data
The remaining portions of the MusicBrainz data are released under the Creative Commons Attribution-NonCommercial-ShareAlike 2.0 license. This allows non commercial use of the MusicBrainz data as long as MusicBrainz is given credit and that derivative works (works based on MusicBrainz CC licensed data) are also made available under the same license.
