Zaz flirts with jazzy styles, French variete, soul and acoustic. Optimism and positive thinking pour out of her and her songs. When she sings she looks amazing. She glows and appears beautiful. It's like she's in her own world where she doesn't care about anything else but singing.
Before listening to Zaz, French was not one of my favourite languages. I had a "few" problems with it in high school. Zaz changed that... Who says that changes in life are difficult?
