I think it can do alright radio/sales wise, as a single, but it's not really going to win back any "lost" fans. It's pop, albeit urban pop (as I said it'd be FYI).
I don't like the Auto-tune on Nicki's singing. She sounds great with her normal singing. And Cassie is decent, but not needed at all. Nicki should have sung the whole thing herself.
If you pay attention to Nicki's badges, they're all mentioning how it's the perfect mix between Urban and Pop. Again, it sounds EXACTLY like Slight Work. I hope you're familiar with that single.
