YouTube is testing a new feature that lets users select videos based on their mood.

Dubbed “Moodwall,” the feature shows a series of video thumbnails under different categories on YouTube’s homepage. They range from the classic “funny,” “cool” and “adorable” to the more quirky “fast” and “catchy,” U.K. newspaper The Guardian reported.

Google has not officially acknowledged the existence of the Moodwall; it’s supposedly being secretly tested on the public, which makes no sense and yet somehow totally works. Since they haven’t acknowledged that the Moodwall exists, they have not revealed how many users have access to it now or if there’s a roll out timetable for the greater YouTubing public.
