In all fairness, though, are any songs by Linkin Park actually heavy? I mean, yes, they do have some songs with screaming, but the scream sections are short and are then followed up by some soft singing or rapping. The instrumentation isn't too heavy either, I think the heaviest instrumentation we have seen is in No More Sorrow and that would still fall into hard rock category to me. I don't think LP will ever make a 'heavy' song, sadly.
