MusicBrainz

MusicBrainz is a project by the MetaBrainz Foundation that aims to create a collaborative music database similar to the freedb project. MusicBrainz was founded in response to the restrictions placed on the Compact Disc Database (CDDB), a database used by software applications to look up audio CD information on the Internet. MusicBrainz has expanded its goals beyond serving as a CD metadata repository, evolving into a structured online database for music information, including details about artists, performers, and songwriters. MusicBrainz captures information about artists, their recorded works, and the relationships between them.
