Kill 'Em All - Metallica latest to do video for every track

Videos, expensive beasts, are for singles. Simples.

But passé.

The Pixies did it, Bjork has done it, and many, many others - including, imminently, kings of thrash metal (sales wise at least...) Metallica.

Yes, the music video remains primarily a vehicle for promoting a single, but, reflecting wider industry changes through digital disruption, now the video is commonly part of a track by track album promo.
