My contribution is OK Go - Obssesion. Printers are actual deamons and that they managed to tame a whole murder of them is so damn impressive. Generally the OK Go videos are really unique and take a lot of actual effort.

Notable mentions are A$AP Rocky - Taylor Swif and although more an animation than a music video, Kaizo Trap.*

Edit: *No, it actually IS the official music video of the song. Neat.
