(Gibson) For a long time, Dave Mustaine didn't have a favorite Metallica song, because he didn't want to listen to his former band. The guitarist-singer, who went on to form Megadeth, was fired from Metallica early on and replaced by Kirk Hammett."I had to do a lot of coming to terms with myself in order to listen to Metallica," he told Revolver. "Before, whenever I heard them, it triggered me in my mind to get up on my soapbox and spit out complaints of what had happened to me. And then once I finally realized, 'Dave, you're lucky, you're blessed, you're in a great band, you're in another great band.' I finally just said, 'You're missing it.'"
Once Mustaine came around on Metallica, he gravitated to one song in particular. "And I remember hearing this song when I was talking to Lars [Ulrich] once and telling him this is my favorite song off the 'Black Record.' And he goes, 'Really? [Expletive], man.' It was 'The Unforgiven,'" he said. "I liked it because I thought this was really the first time I've ever really heard James [Hetfield] sing. He had sung before, and he was a great singer. But that was the first time I ever heard him really, really sing." more on this story
