Thanks for clarifying that with me, @localecho.
It looks like that is a station based off of a composer.
Composer stations are stations curated by Pandora, and they behave a little bit differently than your own personalized stations. One difference is that you cannot Add Variety to these stations.
While there was once a bug that allowed users to add additional artist/song seeds to their composer stations, that bug has since been resolved.
At this point, it is no longer possible to edit the name of these stations, or to add variety.
That's because Adding Variety could change your listening experience on these stations; added seeds would most likely inspire music outside of the scope of the intended genre.
That said, when listening from a computer or mobile device, you can access Pandora Modes to customize your station experience. You can pick different modes like Crowd Faves, Discovery and Deep Cuts.
For more information on Pandora Modes, you can view this page.
Hope this helps!
