Why does everyone tend to forget that both Taylor and Rihanna smashed together in 2012-2013 with WANEGBT-Diamonds and IKYWT-Stay? So there's never gonna be a Taylor vs Rihanna battle, they don't even appeal to the same demographics imo. Taylor has a huge following which guarantees her huge debut weeks all the time but Rihanna is dependent on the radio, she always climbs up the charts so slowly. I don't think she's ever had a lead single debuting with more than 300k downloads, please correct me if I'm wrong.
