Right click anywhere on the page and choose View Page Source in the context menu, and scan through the code, usually you can find string that looks like a playlist url (.pls, .m3u, an IP address sometimes, etc).
This seems to be the url here:
meister.setItem({
src: 'http://audio.true.nl/qdance-hard',
mediaType: 'audio',
type: 'mp4'
});
So just use
http://audio.true.nl/qdance-hard as the url and wait a few seconds for MusicBee to fetch the station metadata (name, bitrate, category).
