https://www.youtube.com/watch?v=fRh_vgS2dFE Easily the most kaleidoscopic entry on this list, the video for Justin Bieber's Sorry (released from his 2015 album Purpose) is so sugary that it should come with a diabetic warning. Though the video is simple in concept (a bunch of young women dance that's it) it's the sheer amount of colour on display that makes it visually memorable. Aside from the colour, the innumerable patterns and textures on the dancer's clothes make it consistently interesting to watch. Not only that, but the song also continued what has essentially become a Bieber renaissance, as the singer's new music fares much better with critics and fans (who aren't teenage girls).
