Open Content Music Database Launched

An anonymous reader writes "The open source music database MusicBrainz was launched officially today. The data is partly in the public domain, partly under an open content like license. It includes artist/album/track information, with more to come. There's support for CDDB-like CD identification (actually, a lot of the current data was imported from freedb), but also identification of single tracks via audio fingerprints (TRMs). Help both in adding new content by tagging your music collection and consolidating the existing data is welcome. Also check out some technical information on the XML database at IBM developerWorks."
