Recently, I'd been listening to music on a radio station I'd made specifically for doing homework while listening to it. I thumb-up a song I was listening to and later, in the same song, it shifted to something that would distract me from doing homework. In response, I try to un-thumbs-up the song, only to find that I'm unable to do so. So I try to thumb-down the song, but I'm also unable to do so. Therefore, it would very nice if the two buttons, thumbs up and thumbs down, would act like toggles for themselves and for each other.
