I know this has already been discussed before to great lengths. But I'm reposting in an effort to bring light to this subject so that Spotify will finally add this feature. There are songs that I have accidentally pressed thumbs up/down but meant the opposite, so the song keeps playing over again in the radio when I don't want it to. Also, users are constantly changing their music preference. The user should be allowed to change their thumbs up/down preference based on their current music preference. Please allow the user to undo a thumbs up/down based on their changing music preferences. Thank you!
