Haunting the Chapel (on Stereogum. Stereogum is a decent site, and similar to pitchfork, but better. They also have this metal blog by Brandon Stosuy. He also writes about non metal music on there too. Good stuff.)
Fenriz (of Darkthrone. His blog and his picks of the year.)
Aquarius Records (my favorite record store, and their lists are usually metal mixed with indie rock, world music, experimental, etc....)
Boomkat (another great record store, but one I have never been to. Just online ordering style. Keeps my ears tuned to the electronic side of things. They also get reggae, sometimes metal, and classical/experimental)
MetalSucks (just got turned onto this site recently. A good one.)
Two other sites I am waiting for year end lists from:
Peacedogman (tons of super nerd lists like, best albums of 1972, and the Buyer's Guide section for their favorite bands. Definitely on the punk and metal side of things - old, but also new stuff as well.)
Teeth of the Divine (writing is probably the worst out of all of these sites, but I still check it once a week for metal happenings and reviews).
