Guayadeque plays some radiostations silently

[Cefn]

A shoutcast station which I'm pretty sure played on a previous build of my machine is now silent. Guessing this is a silent failure due to a codec problem, as other stations play fine. The Alert box indicating the Artist and Track playing works correctly, so there must be some genuine stream running.

An example of this failure is FreePartyRadio.com which seems to be streaming correctly when approached from another service, but when attempted to play from Guayadeque it's silent...

One feature request related to this is that I cannot see any of the metadata associated with a Shoutcast entry within Guayadeque, so I can't literally debug e.g. the URL which Shoutcast actually presents because it's not visible through any of the UI.
