I have had success with SOME of the stations on icecast.com,
shoutcast.com, vorbis streams (xiph.org), of course, and many others.
Sometimes certain stations won't work, but others do.
Or just go directly to the website of the station you want. Often you can access it from there.
Try the CBC at cbc.ca. They even have ogg vorbis streams for their am
and fm broadcasts and the french am/fm counterparts at src.ca should
have the same (I listen to them in my car a lot and they're not all
talk).
Streamtuner, of course, and kde radio station (apparently a version of
it is included in amarok, but through the amarok interface it is
difficult to 'tune' new stations).
