Mutant Sounds and Allegory of Allergies.
Both of these blogs have tons of amazing, obscure stuff. The Allegory of Allergies guy seems especially to have similar taste as me.
I know it's problematic to download music without paying for it, but a lot of this stuff is from rare, out of print old records that I never would have heard of otherwise and which you probably couldn't buy even if you wanted to.
Another good one is Experimental, Etc., though that one has a lot of more recent releases too, so I feel a little guilty promoting them. As long as I'm here, I'll also plug Pyrolyse Bred, a blog of mainly 90's indie-poppy stuff, which I do have a soft spot for.
