I haven't been too impressed with the 2012 albums, and several of my most anticipated records - the new releases from Japandroids, fun., Best Coast, and Ariel Pink - were enormous disappointments.
Honestly, I think Not Your Kind Of People by Garbage is still my favorite 2012 release front-to-back. All of the other albums I've listened to have just had two or three songs on it that I dig.
EDIT: Add the new album from The Presets to my list of 2012 disappointments. Eeesh.
