TBH I got the impression this player is intended more for those who aren’t as skilled as you are with coding and use CMS software like WordPress (some versions of which can integrate with forums).

With this you can put the player on a separate page or a “custom HTML widget” with the iframe and it works, at least for PC’s with Windows/Linux (my Android tablet just shows some box looking for a plugin but doesn’t say what it is).

Maybe you could link the player from a forum menu in such a way it appears in a new tab/window, so the users can still get back to the original forum without risking stopping the stream. (I prefer sites that do not suddenly blare out music without warning in case you are listening to them at work, or maybe listening to something else) – or even use WordPress as a “wrapper” for all the different forums (that is how I would do such a thing, as anything else gets too complicated for me).

Even many radio station sites with embedded players go pear shaped if you move from one bit of the site to the other, the stream is interrupted and/or restarts. TBH if I want to listen to an online radio station I’d use one of those lists like you posted and my own local software rather than the built in players as I am curious about such things as formats, bitrates etc (I thought SLAM!FM was using a low bitrate!) and many of the players don’t seem to work with android (I don’t want to have to install an app for each station and Tune In uses too much memory for smaller devices).

I think (am not 100% sure) the “black page with the player” might be the low bitrate version for mobile devices, which only contains the PVR streams anyway rather than the others although they have mobile links too.
