Rhythmbox is a free software audio player by Gnome, which is also available in the KDE desktop. Available by default through the program manager of many Unix-like platforms.
Rhythmbox is an audio player that plays and helps organize digital music. It is free software, designed to work well under the GNOME Desktop using the GStreamer media framework. However, Rhythmbox functions on desktop environments other than GNOME.
Searching and sorting of music in the library is supported, and playlists may be created to group and order music. Users may also create smart playlists, ones that are automatically updated (like a database query) based on a customized rule of selection criteria.
