Doodah is a collection of two programs to manage a database of MP3s. It stores information in a MySQL database and has a nifty GTK-based program to play them back like a jukebox. It can control XMMS or you can use any command-line player to playback the MP3s. It also allows you store your MP3s on a remote server with the SQL database and use XMMS to stream them over HTTP.
Doodah was written for my own personal use but released on the GNU General Public License in case anyone else finds it useful. Thus it is being developed very slowly with releases only when I think of something new I would like it to do.
