Here's a site with a database and program for organizing your music .
MusicBrainz is a community music metadatabase that attempts to create a comprehensive music encyclopedia. Automatic Audio CD and digital audio track identification using community supplied and maintained data is the first goal of MusicBrainz.
In the future, MusicBrainz will have a genre system and a comprehensive geneology of music, tracking not only music releases, but also detailed information about who contributed to a piece of music. MusicBrainz will keep track of which artists/performers/engineers contributed to a piece of music, and when these contributions took place. The system will also keep track of artist influences on each other and many more pieces of information to create a comprehensive geneology of modern music.
To get started using MusicBrainz, take a look at the search page. For a more in-depth view of MusicBrainz, take a look at the introduction page and the information pages. To get started contributing to MusicBrainz, please look at our contribute and moderation introduction pages.
