Partition is arguably one of the best songs( in my opinion the best one) of Beyonce's career, but would've it smashed harder if it was from Britney with some decent promo? BJ was supposed to have that sound after all..
I actually think it might have smashed (or at least gone top 20). If Britney released it it would have got airplay on pop radio, and Partition is such a catchy song that if the pop audience heard it I know they'd love it. It's a great club song too, and Britney did similar songs like I'm a Slave 4 U and had hits with them.
