Wanted - lightweight program to play internet radio audio streams - especially BBC

[Chris Green]

I'm having very little luck in finding a reasonably lightweight program
to listen to live radio streams, in particular the ones from the BBC.

I don't want/need any form of playlist, GUI, etc. I just want to be able
to feed an audio stream URL into the program and get to listen to the
live broadcast.

I don't want to have to run a browser to drive it either, ideally I want
a command line (i.e. no GUI, no need for X) program but maybe that's
being a bit too hopeful.

The BBC provides its live streams as .asx amd .sdp files/URLs, there are
alternative sources streaming some of them as .pls streams.

I have tried 321mpg - fails completely, 123mpg sort of works but not
very well, mplayer is far too heavyweight and vlc doesn't seem to
support any of the BBC streaming formats.
