DataMPX [lifetime]   
by MPX center   

DataMPX is a tool that lets you catalog your MP3 music collection, regardless of it's being on your hard drive or on removable media, say, ZIP disks or CD-Rs. The tool has a gorgeous interface and is pretty easy to use and understand. You don't have to type all your collection in the program - the tool is smart enough to import all the information from ID3 tags of your MP3 files.
You can group your collection into several subsets and customize the general appearance of the program. The tool comes with a powerful search feature - now you don't have to browse through hundreds of tracks to find the right one!
