Yeah, I've heard a few Master of Puppets comments alright, heard one person refer to DM as Justice of Puppets! Theres no way it'll ever compare to Master of Puppets but they've made a hell of a good attempt. I reckon its more like the stuff on Justice.
I can see what you're saying re it needing a few listens Cahir. The first time I heard 'The Day that Never Comes' I wasn't mad gone on it but it has really grown on me. Its the new One. Have to say I like alot of the other tracks on the album on first listen. They've definitely gone in the right direction with it, I believe.
