Why are we criticizing her. How many such English songs became very famous in past two to three decades. Even if you take B and S songs , except few majority are like this. In this world totally unwanted /unacceptable things became world famous eg Coca Cola . At the same time very good quality things were totally rejected or rejected intially eg. Toyota Lexus, Honda C90 etc. Some of the best inventions took long to get recognition. So we are living in such a world and Yohani and all singers in English and any other is no exception.
Only thing I could say for this video is she is trying very hard , which is good, though I do not like her voice.
