I was able to get a message that the stream was not responding and to try again later.
You have to be logged into Spotify or Deezer to play the full track, and as I haven't signed up to either of them, I couldn't test if just logging in to the site with your normal browser, will let MB play the tracks.
BTW...
just copy/paste those samples into any text editor (like Notepad) and save them as an .asx file.
You can then import them into MB to test them out.
