When a song is aired, both the artist and the song itself cannot be aired at the same hour within a specified number of days.
After this number of days, artist/song can be chosen and aired again in that hour.
You can set a number of minutes within the "same time" check should be done. For example, if 60 minutes is chosen, the song or artist cannot be transmitted at that hour with +/- 60 minutes of difference.
i.e. if a song or an artist is aired today at 10:00, the same song and the same artist can't be aired tomorrow if chosen between 09:00 and 11:00.
The choice of the difference in minutes and the choice of days to analyse are separate and can be configured in Edit > Settings > Rules.
