Interesting.

I did a wget on the stream and saved a number of Kbytes.

rename to extension of ".aac" and then tried both mplayer and ffpplay.

The "aac" extension mean mplayer/ffplay attempt AAC decode and when it
fails, they try other other formats.

It plays OK as a MP3 320kbs stream - scroll down to red text
