Here's my definite top 5 for the year thus far:
1. Boris - Smile
2. Nine Inch Nails - Ghosts I-IV
3. Opeth - Watershed
4. Motorhead - Motorizer
5. Judas Priest - Nostradamus
Other contenders for my year-end top ten would be the new In Flames album, as well as the Eluveitie and Torche albums.
edit: Though I still haven't heard Death Magnetic yet, and it's sounding like it might have a chance
. And there's a few more albums that I'd like to hear other than that one as well.
