I'm not sure what the proper protocol is (if there is any) for linking another blog that freely shares copywrited material, but
this guy's got a healthy dose of zip files with obscure and popular quiet storm jams.
If I wasn't in such a bright summery mood I would be downloading these files like they were going out of style. The text and formatting of the site is a nightmare to navigate, but think of it like a challenge on an old Nintendo game: sometimes you have to find the magic whistle before you get to go to the warp zone.
