This is the Amen Break. You've probably never heard of it, yet have listened to it hundreds of thousands of times. Here it is, and a history: [youtube]5SaFTm2bcac[/youtube]
Yeah I learnt about the Amen Break a few years ago. It's actually amazing to think how many songs have spawned as a result of a simple six-second drum loop.
Every weekend, I play a game where I turn on this breakbeat station, and try to see how many songs I can hear that feature the Amen break. Usually, it's 4 out of every 10 songs. Also, I'm pretty sure that if you listen to The Perfect Drug, there's a variant of the break in there.
