I have followed the Live Radio Wiki Link to configure live radio in XBMC but for both an ordinary URL and .M3U I get an error message that states "Playback Failed, one or more items failed to play". Is there something I'm missing?
The actual links are - http://www.classic97.net/index.php?file=c-listen
and http://www.smooth981.fm/smooth981.m3u

Any help/pointers please.
