This song is not the first collaboration song of Metallica but the first one with a rapper. Actually Metallica and JaRule did not work in the studio together. The producer Swizz Beatz just sampled a few not yet released Metallica riffs and JaRule rapped over it.

Album:
"G.H.E.T.T.O. Stories" rap compilation

Album info:
The Met+JaRule song is actually the only one on this compilation in which can be guitars heard. The album was released on July 16th 2002.

Swizz Beatz about the collaboration:
"I knew I wanted to do a rock ‘n’ roll track and I knew I wanted to get the biggest act possible to do it, but I never thought in a million years that I’d be working with Metallica on this. They had two songs already that I really liked. I took those and combined them into one song. Then I called Ja Rule and told him I needed him to be on what could be the biggest song of his career. I told him to guess who he’d be working with on it and he was naming all these people he thought it was and finally, I said, "It’s Metallica," and he said, "Hell yeah!" This song is a blessing. When people hear it, they won’t believe it!"
