I was wondering if anyone could give me ideas as to why Genghis tron was rejected for not being metal enough. That and being new to a site full of metalheads, which is something I've been looking for for some time now, I wanted to know if anyone had an opinion on this band

There's a thread for this in the suggestions and complaints section.

They were probably excluded due to not being metallic enough by MA standards. Bands like The Locust, Agoraphobic Nosebleed and Last Days of Humanity also aren't here.

Playing random noise on your guitar while screaming randomly and blasting doesn't make you metal. You need something more than this. This band is more or less a less metal version of I Wrestled a Bear Once, who is already fairly borderline.
