Adding tracks to the On-Air list:

From a source tab (Song, VoiceTrack, Jingle etc.):
Select one or more files in the source tab.
Right-click and choose 'Insert as next' (X in the menu) to insert directly after the current track.
Or drag and drop the files onto the On-Air list.

The changes are sent to RadioBOSS immediately.
The list is refreshed after a short delay to show the confirmed state.

Note: Only audio files and supported commands can be added to the On-Air list.
