Autogg started as a music player that also sorted your music and presented it in a nice list based on albums, like a jukebox. Originally it only played files of the ogg vorbis format.
Now it is sorting both mp3 and ogg files, but the playback is done by xmms, or you can use drag and drop with other players.
Current version is 0.6.0, and adds mp3 support, but does not include player.
