Well, I haven’t had any success either. My attempts to even get to the website were blocked as a potential attack by some service they are using.
I tried to track down details of the direct stream without success - the request for an aac stream doesn’t seem to ever get a reply, even though it shows as playing in the browser.
I suggest you drop them a line and see if they can provide a direct URL that we could add to the Live Radio directory (NB we cannot add TuneIn streams to the directory)
