From the developer: "Keeps track of MP3 and OGG files stored on your hard disk, CD's, LAN etc. Tree style browsing, powerful search, modification of tags of several files in one operation, file renaming, playlist editing, collections, preview mode, advanced 'drag and drop', and much more. My MP3 Organizer uses a multiple document interface, which allows the user to have many different 'views' open simultaneously."
