freedb is a database of compact disc track listings, Where all the content is under the GNU General Public License . To look up CD information over the Internet , a client program calculates a hash function from the CD . If you have any questions or concerns, please contact us at the following address:
It was originally based on the now- proprietary CDDB (Compact Disc DataBase). Because it is inherited the CDDB limitations,   there is no data field in the freedb database for composer. This limits its usefulness for classical music CDs. Also, CDs in a series are often introduced in the database by different people, resulting in inconsistent spelling and naming conventions across discs. As of April 24, 2006, the database held just under 2,000,000 CDs.  As of 2007, MusicBrainz – a project with similar goals – had a freedb gateway that allows access to their own database. 
The original software behind CDDB was released under the GNU General Public License, and many people submitted CD information thinking the service would also remain free. The license was later changed, however, and some programmers complained that the new license included certain terms that they could not accept: if one wanted to access any CDDB-like database (such as freedb) , And any programs using a CDDB logo while performing the lookup. 
In March 2001, CDDB, now owned by Gracenote , banned all applications from accessing their database. New licenses for CDDB1 (the original version of CDDB) were no longer available, since Gracenote wanted to force programmers to switch to CDDB2 (a new version incompatible with CDDB1 and hence with freedb).  The license change motivated the freedb project, which is intended to remain free.
Freedb is used by media players , cataloguers, audio taggers and CD ripper software. As of version 6 of the freedb protocol, freedb accepts and returns UTF-8 data.
On July 1, 2006, two of the main freedb developers resigned.  Though this was a worry over the future of the project, it was announced on July 7, 2006  that the plans were in place that would most likely find freedb a new home and it would continue its operation as normal.
On October 4, 2006, freedb owner Michael Kaiser announced  that Magix had acquired freedb. On June 25, 2007, MusicBrainz – a project with similar goals – officially released their freedb gateway. The lath Allows users to harvest information from the MusicBrainz database Rather than freedb.
