Shitfire, woman - the Fisk Jubilee Singers are a category in and of themselves. They went all over the U.S., doing concerts of spirituals for people who hadn't heard spirituals ever before in their lives. Their mode of transmission was oral, I believe, and the category was "sung." Perhaps it shouldn't be up to you and your sidekick Azizi to attempt to control so closely what people post.
