Gaga drives her publicity by polarizing listeners, thus she must constantly top herself to keep feeding the fire. Her fame will dwindle at some point, but not until the haters develop more of a "who gives a shit?" attitude and quietly ignore her. "The Fame Monster" is an aptly-named album. Her schtick works perfectly, and as a result, she's almost universally known. In China last semester, "Poker Face" and "Bad Romance" were just about the only songs that my Chinese and American friends all knew. Music-wise, her songs serve their purpose. They're energetic and catchy, good for dancing and socializing but not particularly useful for actual listening.
Also, kudos to her for capitalizing on all the "she's got a dick" nonsense. Does it matter in the slightest what genitalia she's got? If people are trying to attack you with shit like that, you take the attention and milk it for everything you can.
Yeah, fuck the void.
