I certainly in no Rihanna Navy but that really was a weak cover! Rihanna's tone suits the song.

You keep labeling Alex as a power house vocalist yet she failed to nail such a simple song by an artist you claim can't sing.

I personally like Rihanna's voice and I think by saying she can't sing is just being pathetic... Rihanna by no means is a Beyonce type of vocalist, but neither is Alex
