I suggest going back further to some of the origins of metal and rock. stuff like iron maiden, black sabbath, led zepplin, testament, slayer, dio, kiss, van hallen, etc.. then again, i'm old so...'you damn whipper snappers and your hippity hoppity metal death noise!'
but seriously, it's a good idea to explore the roots of the music you like.
This x1000000!
once you get a feel for the classic stuff, the newer stuff just sounds bland. Might I suggest some Judas Priest, Megadeth, Overkill, Motorhead, maybe even some Pantera. Most importantly, don't limit your tastes. There is a vast collection of Metal sub genres to go through!
one last suggestion, it's not Metal, but Maybe try some Rush, they are fucking amazing!
