Apparently unsatisfied with their comments on Avenged Sevenfold, Underoath is now setting their sights on Metallica. The band spoke to Metal Hammer saying:

When we were on tour in 2006/7, the tour manager for Anti-Flag was talking to me, and he asked what my favourite Metallica record was. I said I didn't have one. Not that I liked them all, but I didn't like any. He was like 'what?!' I said I didn't like them, I didn't think they were any good. He got really startled then almost offended. He was literally slamming the bar saying, 'there is no F-ing way you play the music you do, the way you do, and not like Metallica'.

I can listen to that stuff, and maybe if I was alive 30 years ago it would mean more to me; I respect them, but I just don't like them. I get that they're important, but not to me. For me Kurt Cobain means more: he played like trash but he had an intensity. It's not about your chops, it's about creating a feeling.

People can say, 'if it wasn't for Metallica, you wouldn't have a scene to play to', I'll give them that, but I still don't like them. Maybe one day I'll look back, having changed my mind about Metallica, and think what a stupid 25 year old I was.

The band released Lost in the Sound of Separation in 2008.
