Well yeah I guess if some of the other genres on there deserved a guernsey then I guess djent might as well be on there as well. How old is this thing, though? It's been getting heat around the place lately but it might've been around for a while. Djent as a non-obscure term is like, a year old, tops.
And Gojira? Not technical?
Really? I mean, they don't fit perfectly in the genre, but they don't really fit in anything
that well. They have elements of a lot of stuff.
EDIT: Actually I've got Gojira in my iTunes Library as "Progressive Death Metal" which makes a little bit more sense. I guess when you consider tech-death as something like Cryptopsy or Atheist, the comparison doesn't make any sense. I mean, they're technical, but not in the same way that a band like Atheist is.
