That radio stream plays nice with AminetRadio on my AmiKit Real setup on WinUAE
http://real.amiga.sk/. You'll find now it already has a lot of radio streams saved, so you just have to press on the Play simbol to start the first.
It will work right to play radio streams with WinUAE or a powerful accelerator like yours. For the rest of people it's also possible to play radio streams with a MAS player and configuring AMPlifier or AmigaAMP, but AminetRadio can't be configured to use the MAS.
