I made about a zillion "best of" lists this year. Here they all are in one place.
Metalsuck - top fifteen: http://www.metalsucks.net/2012/12/04/grim-kims-top-fifteen-metal-albums-of-2012/
Pitchfork - best albums/songs: http://pitchfork.com/features/staff-lists/9017-the-top-50-albums-of-2012/6/
American Aftermath - best demos: http://americanaftermath.net/2012/12/22/best-of-2012-grim-kim-kellys-favorite-demos-of-2012/
Unhallowed Nation - best ugly death metal records:
More are still waiting to be published, notably Brooklyn Vegan and Burning Ambulance, (or in Cvlt Nation's case, written - whoops) and a few are floating around in print form - Terrorizer, Absolute Underground.
I also lauded Pallbearer's stunning 'Sorrow and Extinction' on Invisible Oranges (http://www.invisibleoranges.com/2012/12/top-50-albums-of-2012-10-to-1/) and Pitchfork (http://pitchfork.com/features/staff-lists/9017-the-top-50-albums-of-2012/).
I really just spent all year listening to David Allan Coe and Venom, but, people like lists.
