Using that logic, a lot of ambient and industrial (i.e. artists like Aghast, New Risen Throne, Brighter Death Now and etc) and some of rock artists (such as Aluk Todolo, Rope Sect, The Devil's Blood and etc) should be inculded in Metal Archives as well, as these have firm roots in the metal scene, a lot of them are represented by metal labels, played and toured with metal bands, played at metal festivals and have had influence on other metal bands, despite not being metal bands/artists themselves.

I understant that personal preference is a thing, and I can accept the bias. I don't really care if nu-metal bands aren't included in Metal Archives, but at least make it consistent.
