What other metal is worth hearing besides Opeth?

My top 5 bands would be:

1. Cannibal Corpse
2. Cryptopsy (minus The Unspoken King)
3. Immolation
4. Nile
5. Death

And other cool stuff like: Augury, Neuraxis, Decrepit Birth, Martyr, Gorguts, Negativa, Defeated Sanity, Quo Vadis, Atheist, Pestilence, Severed Savior, Pavor, Necrophagist, Spawn Of Possession, Hate Eternal, Arsis, Meshuggah, Terminal Function, Visceral Bleeding, Gorefest (early), Polluted Inheritance, Watchtower, Spastic Inc, Blotted Science, Coroner, Sadus, Deathrow, Sepultura, Sacred Reich, Slayer, Celctic Frost, Megadeth, Testament, Fates Warning, Forbidden, and tons of other bands.
 
If you are referring to my list; i guess it's all subjective. But those are some of my all time favorite bands.
 
Ayreon
Dream Theater
Iron Maiden
Megadeth
Old In Flames
Old Children of Bodom
Old Norther
Kalmah
Stratovarius (depends on the listener, it's mostly symphonic powermetal)

If some "punk" or thrash influence doesn't matter then remove the "old"'s.
 
this is not nearly as creative as many other peoples suggestions, but Anata: The conductor's departure is ripping my face off right now.

They opened for In Flames last week and I decided that they're pretty awesome as well. Put on a better show than In Flames sadly enough, since they didn't play any good old songs and relied way too much on fancy light shit.

From almost every account I've seen, Gojira absolutely SLAYS live. Can't fucking wait to see them myself.
