I don't think it's you, but Centova that's the problem.
I have a webradio too and they do their hosting through Centova.
There are always issues with the player:
the metadata always take a long time to update, and after a while, they stop updating altogether.
On top of that, you are lucky to have got this far, I have tried anything and everything, but I just cannot get any audio player to send the metadata through even though I am doing everything correctly.
