MusicBrainz Database

The MusicBrainz Database is split into two components for licensing purposes.

Core data
The core data of the database is licensed under the CC0, which is effectively placing the data into the Public Domain. This means that anyone can download and use the core data in any way they see fit. No restrictions, no worries!
Supplementary data
The remaining portions of the database are released under the Creative Commons Attribution-NonCommercial-ShareAlike 3.0 license. This allows for non-commercial use of the data as long as MusicBrainz is given credit and that derivative works (works based on the CC licensed data) are also made available under the same license.

For a breakdown of what constitutes core/supplementary data, view the MusicBrainz Database page.
