As of September 2020[update], MusicBrainz contained information on roughly 1.7 million artists, 2.6 million releases, and 23 million recordings.[2] End-users can use software that communicates with MusicBrainz to add metadata tags to their digital media files, such as ALAC, FLAC, MP3, Ogg Vorbis or AAC. Since 2003,[11] MusicBrainz's core data (artists, recordings, releases, and so on) are in the public domain, and additional content, including moderation data (essentially every original content contributed by users and its elaborations), is placed under the Creative Commons CC-BY-NC-SA-2.0 license.[12] The relational database management system is PostgreSQL. The BBC online music editors would also join the MusicBrainz community to contribute their knowledge to the database.[15] On 28 July 2008, the beta of the new BBC Music site was launched, which publishes a page for each MusicBrainz artist.[16][17] ./cache/en-wikipedia-org-9152.html ./txt/en-wikipedia-org-9152.txt
