Amen Break

I love Democracy Player (maybe because I don't have cable). It has some really crappy stuff and some really good stuff on it. Checkacheckitout: it is basically just RSS feed TV.
One of the more interesting things I ran accross while having it playing in the background was the history of The Amen Break.
Wikipedia:The Amen Break is a break beat that has been sampled more times than Pepin's mom and is just plain awesome. It also says alot about copyright and the importance of the public domain. (FYI: Pepin's mom is also public domain.)
