Abraca is a XMMS2 music player. It is designed with collections in mind, which makes managing your music a breeze.
XMMS2 borrows concepts from XMMS-era music players, such as playback control, a playlist, plugins, user-configurable GUI, and adds features that were starting to appear in media players around 2001 and 2002, such as a Media library and a Client-server based media player.
