In my opinion you already have good taste in music, so I'd also suggest just getting more into the bands you've already listed (if you haven't already).

Your music taste is bad.

Instrumentals?

Please... Never listen to any of those bands again if you truly care about music. Listen to the Big 4: Anthrax, Megadeth, Slayer, and Metallica... I encourage you to look into Exodus, Pantera, Osmius (only found on YouTube from what I can see), The Law, Motorhead, Battlecross, Speedwolf, Testament...

If you want darker stuff: Lamb of God, Enslaved, Slipknot, Unearth, whatever... You'll figure shit out yourself but I've got too many bands in my vocabulary to sit and list them. No more vag-metal...

ok, don't listen to that guy, you taste in music is fine, and you might like bands like-
evanescence
disturbed
system of a down
dream theater
rise against
five finger death punch
rev theory

The Fritzklenners.

Apocalyptica is definitely something you would like if you like heavy instrumentals. And they do it with cellos instead of guitars. It's really cool. Look up their version of Enter Sandman.

MY CHEMICAL ROMANCE !!!
they are my favourite band :3
my fav songs by them are:
the end
dead
mama
house of wolves
helena
cancer
our lady of sorrows (probably their screamiest song...they dont scream much)
umm ill stop there because ill probably end up listing every one of their songs cuz i love em so much <3
