You can use Track/Artist Separation Playout Policies to prevent artists from playing too close together in your playlist. This feature allows you to set minimum time periods before the same artist can be played again.

To set this up, navigate to Manage > Playout Policies in PlayIt Live and click Add New. Select Track/Artist Separation Playout Policy from the options. In the policy settings, use the up and down arrows to set the Artist separation time - this is the minimum number of hours or minutes that must pass before an artist is played again. You can choose between hours and minutes using the dropdown menu. For example, you might set this to 2 hours to ensure sufficient variety between artists.

You can also apply the policy to specific track groups by checking the Apply to specific track groups checkbox if you only want the separation rules to apply to certain types of content like songs rather than jingles. Additionally, if you have artists that are related (like solo artists and their bands), you can set up Related Artists in the system so they're treated as the same artist for separation purposes - for example, preventing Robbie Williams from playing too close to Take That.
