Hip hop artist Shock G make an analogy between sampling and taking a picture.
Perhaps it’s a little easier to take a piece of music than it is to learn how to play the guitar or something. True, just like it’s probably easier to snap a picture with that camera [looks at camera] than it is to actually paint a picture. But what the photographer is to the painter is what the modern DJ and computer musician is to the instrumentalist.
