In the early days of electronic music, sampling was considered theft. In this video from 1988, Fresh Prince — sorry, Will Smith — Jazzy Jeff, Cold Cut, De La Soul and even Tom Petty try and get to the bottom of the question "is sampling art or stealing?"
It was shown as a news segment on Australian TV in the 80s, though it looks a lot like it was made in the US, possibly by MTV. It's interesting to see the reaction of some music industry insiders, who appear upset by the idea that another artist could use part of their song to create a new one. Two decades later, and their tiny little minds would be blown by file sharing. I bet stealing a riff doesn't seem as bad now, right? [KevinIntensity]
