XfreeCD audio CD player
XfreeCD was one of my first Linux projects, it is a audio CD player application that takes its visual design from Nate Smith's freeCD. Development of XfreeCD stalled when I switched to using xmms to play all my music after ripping all of it it to ogg format using Grip.
Current development has been moved to a Source Forge project. Check there for the latest versions.
XFreeCD features a simple, borderless playback interface, CDDB song database support, GTK+.
