Since when was Blackout a successful album?
And how does it even compare to anything that's relevant today?
Whenever we talk about Rihanna, stans bring up Beyonce and vice versa.

Now for Christina, the opposing side is Britney.
This is getting really silly and childish.

At least have a relevant argument that doesn't revolver around

-The Grammys
or the -Billboard 100 Chart for the US

..Or around an album that no one talks about anymore.
