Thanks for sending that over, @grrlwhit03.
It looks like a playlist was shared with you - not a station. Thumb ratings are only a feature when listening to stations - not playlists.
Stations on Pandora Premium are guided by thumb feedback or added seeds, like Pandora and Pandora Plus stations. While listening to a station you can thumb up or down songs from the Now Playing screen to help us learn what to play next. Playlists, on the other hand, are guided by listener's choice. This means you can add only the songs you want to hear, and sequence the playlist yourself.
This being said, no further action is needed on your end to make this playlist your own. It looks like that playlist is already a part of your collection.
Hope this helps clarify!
