On-Air playback functions:

Execute entry immediately:
Select an entry in the On-Air list and choose 'File > Execute Entry' (X in the menu).
RadioBOSS starts this entry immediately; the currently playing track fades out.
Confirmation is required.

Stop overlays:
'File > Stop Overlays' (Y in the menu) - stops all currently running overlay tracks.

Note: These functions require a configured RadioBOSS API connection.
