Rihanna & Paul McCartney & Joke - Four Five Seconds

When I first heard that Rihanna and Paul McCartney created a song together, I though "cool, might be interesting". Then I realized that it was also made with a dude called Kanye West... I really don't like that guy and his songs, so I thought it can't be worst.
The effect you can find here:

What do you think? I think it would be perfect if Kanye would disappear from this song. Rihanna is bringing her lovely voice, Paul his soul and what do Kanye do?? He's singing is giving a lot to think about (for example - how to stop kids on time from doing what they THING they are good at, and many more) He is not bringing to this song anything! And in the music video - good God, why?! He is just shaking and trying to be cool, in this song.
Do you agree?
