AudioManage extends Windows and adds a powerful audio library to any Windows app, offering a completely novel way of managing audio. It has a powerful, unicode mp3 id3 tagger as well (also for wma, ogg etc.), and can handle tags of the format ID3, Vorbis, WM/* etc., and files like MP3, WMA, ASF, OGG, AAC, M3U, WPL etc.
Unlike other similar applications, the virtual folders views of AudioManage are REAL to Windows, and can be browsed in any Windows app - no need to run any separate program to use the library - even right in the File->Open dialog box of any application. All standard Windows shortcuts (cut, copy, paste, delete etc.) work, even when the library is used from inside Windows Explorer!
You can manage not only files on your computer, but also on the network, removable drives, mp3 players, ipod etc.: anything that has a filename and path can be added to the library. It also indexes AudioCDs, and can retrieve CD covers and album & track information from online sources.
