re: "http://mediaweb.musicradio.com/Show.asx?StreamID=2"
This is a playlist URL. You can listen to it using mplayer with the following command line (ie in a terminal window):
mplayer -playlist "http://mediaweb.musicradio.com/Show.asx?StreamID=2"
The other URL listed in the post from chazzy2501 probably came from here: Listen Live Online to Classic FM - RadioFeeds UK & Ireland Search
which lists a variety of different audio qualities. Some of the links shown on that page are also playlists - specifically those ending in m3u.
