I'm always fascinated with the amount of people who are impressed with Nile's historical facts. It's great that they've done that, but it's no different than what a grade school student does, and really speaks more to the lack of thought put into the lyrics on the part of other bands, than on the seemingly difficult task done by Nile.
As for gory lyrics, they work when their used as details within the whole of the topic in the song. When they are used as the point of focus, that's when it distracts and loses meaning, imo. Sexual exploitations of women in lyrics are childish and ape-like.
