If you ask any guy about what he would connect with skandinavian metal, he would probably tell you something about death metal and grim guys eating young children.
German metal stands for Rammstein or 90s glam/trash/speed metal like Sodom, Blind Guardian, Kreator, Gamma Ray and so on..
If you would ask me about metal and Japan, I would say something with female looking guys.
And everyone connects american metal with metal core or nu-metal or whatever. So even metal + rap + downtuned guitars + clean vocals like LP or Limp Bizkit or some gay metal core bands like Attack Attack! Or Metallica.
And atm there is a thin line between gay looking american rap-metal guys and Alexi, his clothes and the song IWC
