Dave Mustaine spoke to LA Weekly just a few days before the release of the new Megadeth album Dystopia. When asked on what's the favourite track he helped write for Metallica's 1983 debut album Kill 'em All (he's got credit on four songs), Mustaine answered:
My favorite? Hmmm. Interesting. Good question. You know, I like “Phantom Lord” and “Metal Militia” because they are very interesting songs. But I think if you were going to go for my favorite Metallica song that I wrote it would probably have to be [Ride the Lightning instrumental] “Call of Ktulu.” It stands on itself. And when you have a song that can stand on itself without words that’s a big statement.
