...obviously Britney can sell out arenas by sleep walking because she's a nostalgia act, people go because they grew up with her, not because she's any good today.
And what's the excuse for why she can't sell albums today if she's been around 13 years? I don't get it. Shouldn't she be able to effortlessly sell her albums and not all of a sudden become on par or LESS than other singles artists Rihanna, Katy, etc, who've been in the game for a few years?
