to do it simply from commandline on the raspberry pi, install "mplayer" : 

sudo apt-get install mplayer

Then use mplayer to play the ITTY stream: 

mplayer http://209.180.212.65:8000/listen.pls 

Most any usb audio dongle should just work once it's plugged in. 
You can (from the command like) use the command "alsamixer"
to adjust volume, etc. 

If mplayer insists on using the useless builtin audio on the pi,
you can run it like "mplayer -ao alsa:device=hw=1,0" to force it
to use the newly installed sound device.
