In the documentary, Gaylor highlighted the works of artist and DJ GirlTalk. GirlTalk specializes in what are called mash-ups. He takes a bunch of songs and creatively place them into one track and it just sounds awesome. Although not all artists go to that extent, they do use sampling which is very identifiable in today’s hip-hop and r&b.

Sampling can even be seen in movies. Different shot techniques that are used can be tracked down to one single origin.
If anyone is interested, the series “Everything Is A Remix” does a great job breaking down how other industries sample and remix. I was surprised to know that even computer companies “borrow” from each other.
