Metallica fans love to complain. They complained when the band made a video for "One" in 1989. They complained two years later when they scored a giant crossover hit with "Enter Sandman." They really went nuts a few years later when they cut their hair, put a photo of blood and semen on their album cover and recorded with Marianne Faithfull. They complained when the band waged war against Napster, and again in 2003 when they made the drums sound all crazy on St. Anger. 2008's Death Magnetic was supposed to be a return to form, but fans complained about Rick Rubin's ultra-compressed mix of the album. How does the band respond to that? They record an album with Lou Reed that most of their hardcore fans are guaranteed to hate. The band has always done exactly what they felt like doing, and it's no coincidence they still pack stadiums all over the world. They must have been doing something right all of these years.
