Library
A channel needs its ID, which starts with UC. On the channel's YouTube page choose Share, then Copy channel ID. Playlist and single-video links work as they are.
Best for takes any of: spring, summer, autumn, winter, morning, afternoon, evening, night, clear, gray, rain, snow. Leave it empty for a station that suits any day. Inside a station, videos whose titles name another season still play, just less often.
