In reply to blue.

Im not here for that excuse. During the 4 era. Bey had Gaga as competion. During IASF, there was Taylor Swift. B Day, she had competition from both Christina and Justin. She still manage to top both single and albums for a sustained period. Im not here for you trying to discredit that. Rihanna has not had heavy competion every era when she released an album and failed to even top the chart at all, let alone maintain it. And no they do not average out at 4 weeks, Single Ladies is her only song to be at #1 for 4 weeks and that was her shortest run. Baby boy was NINE cosecutive weeks, Crazy in Love eight, Check on it 5. All this comes down to is, Beyonce has a good feat that is not easy. And when Beyonce tops the charts, she can maintain it better than Rihanna. Deal.
