Animation in Music Videos

I'm leaning more towards the indie rock genre however in researching the indie genre more broadly I've found various quirky videos. The fun and upbeat tempo of the Of Monsters and Men song Little Talks perfectly suits the quite random, childish nature of animation chosen to be used in the video. 
I was really interested in the use of colour in high saturation amongst black and white footage that makes up the majority of the video. Personally, having listened to the song first I would not have even thought of using black and white due to the more mundane mood associated with such.
