I used to be able to do this with ease on the desktop website. However now, the Add Variety button is gone, even though the instructions on their own site say it should still be available:
Click on the My Stations tab, then hover over the album art of the station you'd like to edit or add variety to. Click on the ellipses (...) then select Station Details.
To add or remove variety (Station Seeds) to this station, scroll down to the Station Created From
- To add variety, choose + Add Variety and enter either the artist or track you'd like to add. Click on the + sign that appears to add that artist or song to your station.
- To remove variety, hover over the desired seed and select Delete.
Note: you cannot add variety to Genre Stations.
The stations I'm trying to add variety to are the stations I've created, not genre stations. I'm a Pandora One subscriber. Has this feature been made premium only? I've not read of this change.
