How do I stop the internet radio playing?

[Ultraviolet]

I successfully added a few radio stations which appear above my folder list. There is a clickable play button next to each station and the stream works fine. However, I can't stop the stream. The stream appears to have no involvement with the integrated subsonic player. In fact, the only clickable item associated with a radio station is that little play button. I assume I'm clearly missing something here.

I found another thread on here that basically said the solution was to click the radio station name, instead of the play button and that would pass the controls to the internal player. However, like most people responding in that thread, the radio station name is not clickable.
