 : This comes up periodically on Metallica's talk page, most recently here. Consensus seems to be to leave the primary genre as heavy metal, as you can't say that everything that Kirk Hammett or Metallica has done in the last 30 years would be considered thrash metal. My recommendation if you would like to see it changed would be to discuss it on Talk:Metallica. If you can convince some people of your point of view and establish a consensus there, I think it would follow naturally to be changed in this article as well. ''''''  "
