I'm looking and have been looking for a sample for about 5 years now. I just want to know where the Radio Tuning sample from the beginning of Dead Prez's Its Bigger than Hip Hop originates from. I have heard the same sample used in many other songs, tv shows and movies such as the movie Radio. It is probably a lot simpler than I have been thinking, part of some stock sound library, because I have heard it so many places but I cannot find it anywhere. Thank you for any help you can provide and below is a link to a Youtube Video with the sample at the beginning.
