Data Crow is a freeware that makes your life easier by cataloging all your collections, be it movies, music, images, books or software.
The beauty of this app is you don’t need to fill put the information in the app, you need to enter minimum information, then it will retrieve other information from Amazon.com, Imdb.com, Freedb etc.
