CDpedia is a CD cataloging application that retrieves all information about your CDs from the Internet via keywords or scanning. It lets you organize your entries into collections and integrates with iTunes to let you know which CDs or single songs you have imported already.
Accessing several international music sites as well as Doghouse, the program's own media server, CDpedia lets you retrieve information about your CDs in three simple ways: either by entering keyword combinations (artist, title, label, etc.), scanning the barcode on the back or inserting the CD into your computer for direct scanning.
Create smart collections and start a wish list for those CDs you don't own yet and a borrowed collection for those you want back. View your entries as a standard list, browse only the covers or use the info view for a personalized look of CDpedia.
