Clip one: This is strained and forced. The only thing that saved her is the backing vocalists and the musicians. I personality don't think that she has a unique sounding voice, the song stripped down makes you realise that the song is all courus Clip two: She tries to emulate Sia's tone on the song which shows as an artist she cannot make a song her own. Again she is substituting shouting for power and is doing the strained constipated noise at the end of each word. Clearly she is better than Ms Cole and Ms Lloyd but thats about it.
