An open source audio database system (Score 2)

Anyone looking for an open source application for keeping data about their CD's, MC's, LP's etc. may look at Project CrossRec http://www.crossrec.org which works with developing an open source (BSD license) front-end and sentral repository for all data regarding audio recording on any medium. The apps are RDBMS based (PostgreSQL and others), and supports data and relations between data not seen in commercial systems.
