Playlist playback functions (via RadioBOSS API):

Play entry:
Select an entry and choose 'File > Play Entry' (P in the menu).
RadioBOSS starts playback from this position.

Execute entry immediately:
'File > Execute Entry' (X in the menu) - RadioBOSS starts this entry immediately;
the currently playing track fades out.

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

Note: These functions require a configured RadioBOSS API connection.
