oh nah crate digger blog was just an expression i made up on the spot.
basically, on blogspot.com, there's a lot of people who make these "themed" blogs where the theme is "vinyl singles". or "east coast hiphop vinyl" etc. if you go there you don't find any albums or single tracks, just full vinyl/CD single rips. I don't remember the names of any blogs like that but googling stuff like "vinyl rapidshare blogspot" and similar combinations should help you out I think.
