Megadeth won the Grammy in the “Best Metal Performance” category for the first time this year after being nominated 12 times for the Grammy Awards. During the award presentation, Metallica’s classic song Master of Puppets was played by the Grammy orchestra.

Dave Mustaine spoke in an interview by and spoke about his thoughts on this subject. He said:

“You know what? I didn’t even notice it. It just sounded like some music in the background. The funny thing is that when I went back and listened to my acceptance speech, and I heard the song, I was, like, ‘Wow!’ Everyone was asking me, ‘What about the Metallica thing?‘ And I said, ‘I didn’t hear it, I just saw it.’ ‘How could you not have heard it?’ I didn’t know what they were talking about.

I thought that they were talking about Metallica’s performance. Because we split [after the pre-televised awards]. By the time they did their thing with Lady Gaga, we were across the street eating dinner. So I went back and listened to my acceptance speech and I went, ‘Wow!'”

I didn’t mind them playing it at all, it’s a house band, and they’re doing cover songs. They were probably saying, ‘We don’t know any Megadeth songs. How about if we do a Metallica song?’ But when I went back and listened to it, I was, like, ‘Oh my God! That’s the worst version of ‘Master Of Puppets’ I’ve ever heard in my life!’
