How do you find good music blogs?

I'm not really sure about blogs, because I never go on them. BUT, I know that if you're trying to find bands with similar sounds or of the same genre as those that you already like, a good place to go is Last.fm. You can go directly to a page for one band, then in the sidebar on the left click "Similar Bands." They give you a huge list and you don't even need to be signed up for the website.
