One-shot command-line sound player that can handle wav, ogg and mp3?

[Joseph Jones <joe@bumpycarrot.cjb.net>]

I'm looking to replace the way KDE handles notification sounds... That 
is, rather than using it's own sound system to noify me using it's 
sounds, using a command-line audio player!

Anybody have any recommendations? Having gotten ALSA working this would 
really tighten my system up a fair bit.
