You want obsessive? Here's your obsessive. And it's updated every day, at least through the end of the year. Give this guy credit. FWIW, I often find things on his personal ten-best list that are worth buying.
Update: The list has gotten so long he had to split it into two. At some point it becomes uselessly large, but I have no suggestion on how it can be made better. A best-of-the-best is kind of silly, because that is just an amplification of his own views. Few of the items on the list could go into sub-categories because the vast majority of the list is "best albums". If you have ideas on how he can improve the list, add them to his comments.
Gaah! He had to split it into four.
Update a year later: Yes, you could have guessed that he would do it again for 2007. There are some nuggets here for those of us who only catch up with new albums once a year.
