Help this noob discover real metal?

Im fairly new to metal, Im more into Metalcore myself (despite it being frowned upon), but I find the likes of Caliban, Chimaira, Bleeding Through, and Hatebreed easy to listen to and develop from.
I also like heavier metal such as Centinex, Slayer, Gojira so I dont just limit myself to one genre.
 
O i forgot to say, I also like some Black Metal too, like Dragonlord, 1349, Enslaved, Zyklon, Graveworm, Dimmu Borgir, Dark Funeral, Darkthrone, Gorgoroth..basically I like to "experiment" and see what styles and sounds I like.
Power metal puts me off though, too many long solo's and girly screams, but each to their own.
