The MetaBrainz Foundation is a non-profit that believes in free, open access to data. It has been set up to build community maintained databases and make them available in the public domain or under Creative Commons licenses.
Our data is mostly gathered by volunteers and verified by peer review to ensure it is consistent and correct. All non-commercial use of this data is free, but commercial users are asked to support us in order to help fund the project. We encourage all data users to contribute to the data gathering process so that our data can be as comprehensive as possible.
The MetaBrainz Foundation believes in transparent finances and is supported by end user donations and a number of sponsors who provide funds in order for the foundation to accomplish its goals. The foundation also has several commercial supporters who make use of our data sets.
