I don't think it needs to be a specific song. If the sound is there, and enough people pick up on it, then maybe they are hearing something others aren't. Breaking it down like: the Bm is conflicting with the A#Major because the 31/32 time signature is not feasible with their style is completely meaningless. I personally don't hear the Metallica much in As I Am, but that's me. People told me I was wrong when I said the opening riff to Behind The Veil sounded almost identical to Creeping Death, yet a dozen people I played it for, without giving them any clues as to what I was doing, heard Creeping Death immediately.
With I Walk Beside You, I hear a U2 influence. But it's not so much where I'd say they ripped them off. It's really arduous to not have influences come out in your music at some point.
