I end up reading tons of blogs about a variety of topics, but I just recently realized that I don't look at any on my favorite topic: music. Does anyone know of any good music blogs out there that are worthy of attention?

Also, would anyone be interested in starting a collaborative music blog? I have tried to do one on my own, but I just don't have the time/discipline to do it by myself. Having others help out when I am uninspired would be pretty nice. Anyone interested?
