Bye gurl. I have no idea why she did this. Her team is deaf? Everyone know that this song doesn't fit to her style and pop radio stations will not play this (I don't say about radio deal in the first few days).
People! I know you like Rihanna, I am her fan too, but this is NOT song for one of the biggest music star! It's just simple accoustic track with simple chord progression and simple guitar rhythmic pattern. Yes, her voice is amazing but it is still simple and boring song. In the internet is plenty of this kind of music. Why other singer-songwriters who wrote something like that are not music stars?
Why did she listen Kanye? Label change was her worst decision. I am pretty sure that she has better material for lead single on R8.
