Hans Zimmer is not original. He'll say that himself. I love him. But one who is too deep into his music will find references.
Picasso wasn't original either. He took inspiration from many places.
You know what is original? A stone age person scratching philosophy on a rock's face.
Everything humans have ever created is built on top of what came before. It's a mashup.
