This is all entirely subjective. Some say she hasn't peaked yet, while others are saying she'll have another peak, which is normal (there are plenty of artists who have had several peaks in their careers).
I do know that Gaga was UNSTOPPABLE in 2009-early 2011. My question: How big was her peak? Was it bigger than Britney's? Madonna's? Michael Jackson's? State your opinions here. And don't give me short, simple answers. I want this to be a full blown discussion.
Discuss, and keep it cute.
