I don't listen to the power or gothic stuff that much anymore, but I do still like it to an extent. And I realize that some of these may be considered more punk than metal, since they fall into the *core category, but eh... If EM recognizes them as metal I'm too lazy to *not* recognize them as metal. Derp.
EDIT: WINDIR! How I forgot Windir I'll never know, but I'm definately adding Windir to the list (and Cradle... xD).
