So, there are some people out there who think Hans Zimmer is good at copying… Even copying himself. 
However, I think he created a great score for Inception and read he was inspired by Edith Piaf’s song ‘Non Je Ne Regrette Rien’ which plays an important role in this film.
Now I found a small youtube movie which shows how he put this inspiration into the score. Listen to that:
Wow, what a find!
wow
