Coherence is a set of DLNA/UPnP devices, like MediaServer and MediaRenderer. In addition, it includes a well-designed framework to extend other applications with DLNA/UPnP functionality. It also has an emerging DBus API, enabling these applications to participate in digital living networks. It supports Playstation 3 (PS3), XBox, and many other devices.
Minirok is a small music player for the K Desktop Environment. As its name hints, it's modelled after Amarok, but with a reduced set of features. In particular, it is designed to cover all the needs and wishes of the author, leaving everything else out. The look and feel is almost identical to Amarok's, though. The main interface is a tree view of the filesystem, with a playlist that can only be populated via drag and drop. There is no collection built from tags, so it's targeted at people whose collections are already structured in a tree at the filesystem level. Searches can be performed both in the tree view and the playlist.
MPy3 is a full-featured, modular, configurable MP3 player system aimed at jukeboxes or car MP3 systems. It can play MP3s via rxaudio or mpg123, take input from a keyboard (tty), LIRC, or joystick. It does output through a CrystalFontz LCD directly, or through any LCD that LCDProc supports, or even through X. It features playlist support and support for controlling the mixer (using aumix). All of the inputs, outputs, and other functions are controlled via a number of modular libraries which can be used in other projects as well.
iCommune is an application that extends Apple's iTunes to share music over the network. It allows you to share the music in your iTunes library and access other iCommune music collections. iCommune music collections appear as playlists in your iTunes window. You can browse through them, and choose to stream or download the music they contain.
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.
