YouTube Radio

YouTube has a feature called YouTube Mix, which automatically creates a playlist with many videos related to the video that's currently playing. Now YouTube tests a new feature based on YouTube Mix: it's called YouTube Radio. "A non-stop radio station based on the current video. You can like, dislike and dismiss videos to tailor  your Radio Station to your taste."

Here are some screenshots that show the existing YouTube Mix feature:
