Looking for metal

I'm relatively new to metal, i've listened to some of the more mainstream ones (Slipknot, Deftones, SOAD, A7x,), and i've enjoyed their stuff, but i'm looking for just a bunch of new stuff. Doesnt really matter to me what subgenre of it, and it can be bands of any popularity level. Really big bands, or maybe smaller ones. Feel free to just give a bunch of suggestions, and maybe categorize them by subgenre? That could be helpful. Thanks for anyone who suggests stuff!
