(CNN) -- The public has been shaking its collective head since rumors of a Rihanna-Chris Brown collaboration began circulating on the Internet last week.
Once the artists' respective remixes, "Birthday Cake" and "Turn Up the Music," featuring each other, hit the Web on Monday, that head-shaking turned into full-blown opposition.
Some have questioned why Rihanna would musically reunite with her ex and whether their working together was a straight career move or a byproduct of her feelings for Brown. But based on the way the "We Found Love" singer markets herself, industry experts agree, her decision to collaborate with Brown is actually quite characteristic.
