Android: How to Edit Thumbs / Stations

[Jazina]

I accidentally thumbs downed a song. How can I undo that because now the song wont play on the station. 

Moderator Edit: Changed title for clarity

Hi. I don't listen to "stations", i use playlists with auto-play enabled. So after my playlist runs out, it continues to play songs similar to the current songs. 

Over the years i have clicked "thumbs down" for many songs. I want to edit those. 

How do i edit thumbs down without going thro "stations"?

Thx, Mj
