Music Manager is a Konqueror plugin that lets you standardize the filenames of your music files, guess information and set ID3 tags from the file's name (this can be done to several files in one shot), rename many selected files based on their ID3 tags, set ID3 tags in mass for selected files with options for copying ID3s from other files and leaving some ID3 fields untouched, rename _ to space and vice versa, create HTML and text indexes of your collections (including total playing time, etc., configurable through templates), create nice CD covers with full listings of your music files (also configurable through templates), and organize your music collection to create a CD.
madman is a music manager application in the vein of Apple's iTunes and its many clones. It serves as a tag editor, a media library, and a CD burning frontend, and is extensible through plugin scripts. Dynamic playlists and powerful search features allow you to listen to better music all the time.
Hayes is the playlist for Noatun that attempts to be efficient for those users with large directories full of music, especially directories futher organized by album. For these users, Hayes should be more efficient in speed and memory than the usual playlist. Plus, the playlist is updated in realtime as the directories change on-disk, so playlist maintenance is no longer an issue. For everyone else, Hayes has some nice features, too: full integration with the KDE global "MetaInfo" system for generic handling of tag information, a fully KDE-standard user interface, proper shuffle behavior with a history, multiple sort modes (including a drag-reorderable custom sort), and nifty checkboxes that let you turn particular files or directories on/off. Two-way Konqueror integration adds convenience to playback and file management. All playlist data is stored in .directory files, which are easily readable and reusable by other applications and tools.
