I'm looking for a free/open source music CD cataloging software that will help manage my CD collection. Ideally, it will be able to pull metadata about the discs from the Internet so that I wouldn't have to type it all into the program manually. If it can scan a drive and locate music files to add to its database, that would be a plus, but not absolutely necessary.
Here's an example of what I'm looking for, although this program is for DVDs only: http://dvdchief.com/
Any suggestions?
