Watch Metallica Build 'Hardwired' From the Ground Up

It's easy to run around, thrashing your limbs to Metallica's new song "Hardwired," so much so that when the band was laying down the swift-paced track in the studio, it song almost ran away from them.

In a new behind-the-scenes video, fans can watch the recording session as they admit they get a little too fast on the in-your-face jam. The clip also shows them laying down individual tracks and explaining the lyrics.
