Since 1983, Metallica have been rocking socks off and melting faces across the world. From their debut album, 'Kill 'Em All,' to their latest studio release, 'Death Magnetic,' the band has always made on thing clear: They are a force to be reckoned with and there is no better indication of that than their epic discography.

If you ask 10 fans what their favorite Metallica release is, chances are you'll get 10 different answers. Some fans are relentless in their support of 'Master of Puppets' while others believe the creative direction and vulnerability of 'St. Anger' makes it a stand-out album for Metallica. Maybe the best Metallica album is the two-disc release comprised exclusively of covers, 'Garage Inc.,' or the live performance with the San Francisco Symphony Orchestra known as 'S&M.' Could it be 'Beyond Magnetic' with its never-before-released tracks or even the band's compilation with Lou Reed, 'Lulu,' that drew a huge amount of criticism?
