There may be some manual data entry on your part, but Music Collection helps you organize all of your music, efficiently, so that you can locate any song, album, or artist quickly and easily. You can create as many collections as you would like and export them in a Microsoft Access format. Even though most of its organization features are already available in actual music players, you might like it if you're really into organizing your music and want to have a separate system just for the details of your entire collection.
Music Collection helps you organize your collection and target any new releases you want to purchase. Sadly, it won't scan your existing files and add them to the collection. You can't import any information from a ripped or downloaded CD, either. Instead, you have to enter all of the information in, manually, or download it from the Web. Once you get the information inside, you can organize it however you like -- by year, genre, artist, and more. Music Collection lets you assign very specific tags to your collection, including its price, barcode, and even sound quality. The program will search for album art on its own, so you don't have to worry about those files. The program's layout is very clean and has one-touch operation for all of its most popular features. If you wish to change the way it looks, though, you can easily do so via Settings -- Look & Feel. There are around 30 skins to choose from.
There's a lot to do with this program, but you can do most of it with iTunes and Windows Media, as well. If you want to keep your collection notes separate from the files themselves, however, then Music Collection is worth try.
