I'm not too worried about happy taking over number 1 on itunes. Katy should still be able to hit number 1 for at least two more weeks. The video will help in streams, and Pharrell still has a couple more weeks til he's able to compete with DH on radio. She's still getting 2m+ daily updates. Plus, her sales will still be high. I see at least 4 weeks at number 1 for a third single as great.. Better than a lot of her peers at the moment
