A currently playing track at the end of a playlist will continue playing so that it's not interrupted by the next event when Overrun is enabled. Note: Playlists with nothing scheduled after them will always overrun, regardless of this setting.
When you have two playlists back to back and the overrun feature is enabled on the first playlist, the current track will continue to play from the first playlist and will not get cut off by the second playlist starting. The track will be able to finish and will fade nicely into the second playlist rather than being cut short.
When you have a playlist scheduled with a Live Event scheduled after it, Overrunwill automatically be disabled so you don’t have to wait for the track to finish. A Live DJ can connect at the time specified and won’t have to wait for the track to finish before they can begin their broadcast.
When you have a playlist with nothing scheduled afterwards, the current track will continue to play and will not cut off when the Default playlist starts (the Default playlist starts when there is no other scheduled playlist or event in the Schedule).
