Jesus, there've been so many Year-end threads mine has been lost in the deep recesses of page 1 in less than 24 hours.
I've decided to do what Natrlhi does... in attempt to justify certain omissions, I will go ahead and announce that I have not listened to the following albums, nor am I going to before the end of the year:
Belphegor - Blood Magic Necromance
Skeletonwitch - Forever Abomination
Profetus - ...to Open the Passages in Dusk (this one isn't released until Dec 31)
Dream Theater - A Dramatic Turn of Events
Dekadent - Venera: Trial & Tribulation
Heiden - Delores (Sorry HB420)
Red Fang - Murder the Mountains
Hammers of Misfortune - 17th Street
These are just some that come to mind that might've made the top 55 had I listened to them. List to begin sometime in the next day or two.
