It's unfortunately (if unsurprisingly) as buggy as the day development stopped. But the UI, and more importantly, the scope (I hate stupid music-library-manager type programs), is just right for playing music, IMHO. Since it was good enough 10 years ago, why wouldn't some people still use it? It's not like playing music has changed.

I have been taking Audacious for a spin lately on my Eee, because it's less buggy, but there's a noticeable higher CPU hit when using visualizations (no plugins, just the scope or FFT in the main window), and it redraws itself agonizingly slow (translation: slow enough I can see it at all) when switching workspaces; XMMS has no visible redraw.

What I really want is a hybrid of XMMS and mpd; with XMMS's input/effects plugins, mixer, etc. capabilities in the server, and an XMMS UI client for control, but with the sane and proper client-server separation, and the ability to use other clients when more suitable, such as for scripting or remote use.
