If any of you are into electronic mixes, my favorite that was released this year was mixed by James Holden, "The Idiots are Winning." To stay with the thread's request, I also liked Thom Yorke and The Mars Volta, previously mentioned.
Muse: Black Holes...
Asobi Seksu: Citrus
and I got to give it up to my boys the Flaming Lips. not only did I enjoy the album, but they put on one of my "top three" live shows that I saw in 06'.
