Kroc - 8 Oct 2004 : This is very simple ogg/mp3 stream player. It might require snack 2.2.8.

There is some streamed radios you can try here: [1]

I tested it successfully under linux with http://64.62.252.140:8628/soulfm.ogg , http://64.62.252.140:8672/divaradio.ogg , http://ogg.tv-radio.fr:1441/encoderfinter.ogg and http://wired.s6n.com:8012

LES: tested on Win 98. The three URLs above work flawlessly. Yay! 8-)

escargo 12 Oct 2004 - I tested it on Windows XP. The first three URLs caused abnormal termination; the last one just produced noise. I downloaded the latest version of snack, and tested it again. No abnormal terminations now, and reasonable sound on three of the URLs (not on ogg.tv-radio.fr).

Kroc 21 Oct 2004 : the same thing but this one doesn't require Tk:
