Have some time to kill? YouTube has just announced its most popular videos of 2015, which include everything from dance crazes to Justin Bieber doing karaoke in a car. You can watch them here.
It’s worth noting that YouTube has chosen the most popular clips not just on the absolute number of views, but by taking into account shares, comments, likes and other indicators of popularity to identify what it calls the ‘top trending’ videos.
Regardless, they still racked up a whole lot of views: YouTube claims that these ten videos alone accounted for 25 million hours of viewing this year. So watching them once more shouldn’t hurt.
