You can personalise any channel in Tunify Plus by clicking on the cog wheel next to the channel. Ideal, but if you filter too much, this can cause more repetition. So check which filter settings you have marked.

Extra tip: You will see a bar when you are in the filter settings of a block. If this turns red, there are too few songs. You should then filter less strictly.

Available with Tunify Plus and Tunify Premium subscriptions.
