It is though. This has nothing to do with when they debuted. It's to do with their relevance today. Both Britney and Madonna are past their prime whereas Beyoncé is still peaking. What's hard to understand about that?
Britney is past her prime but the difference between her and Madonna is that one is in their 30s and the other is 50 something
My bad. I meant to type "GaGa is duh kween of pawp!! Madonna culd nevuh!!! Yass, Gaga, yasszzdzsz!!1! Slay with ur 350M rekurds zold, kween! Brittany hew?"
Is that more along the lines of what you were thinking?
Can't wait for 2016 where we can compare Britney and Bey once again based on their chartperformances and sales in this particular year. I think Bey might beat her once again, just like she did ever since she went solo.
