If Britney and Circus equals 0.5 then no rihanna era amounts to anything besides GGGB and Loud.
Whether an era is successful or not depends on how it lives up to the expectations. So Rihanna her debut era was somewhat successful and her second era was successful. She's lucky to have had a slow start.
The BITCHney era had no hits and sold on her name alone. ARTPOP.
Is that supposed to be a drag?
The GODNEY era sold on her star power and performance skills and the tour was a hit too Slave still sold 5 million despite being radio banned. It also helps that the album sold more than Loud and TTT put together.

In what world was Music Of the sun successful or A Girl Like Beyst
Pearl is like the best song honestly
