Hi! Thanks for reaching out. Let me inform you:
At the moment, the plugin does not include functionality to detect which song or frequency is currently being played, however, this is something that could be added in a future update of the plugin.
Regarding your second question, the system currently allows you to block entire Playlists, but not individual tracks.
This means you can make the radio only play the desired station if a specific Switch is ON. Otherwise, the station will not appear in the list and white noise will be played instead.
I hope this clarifies your questions. Have a great day! ^^
Best regards,
Undermax
