Depends. How many people actually cared about michael jackson before he died? Sure, he had a big dedicated fanbase but it took for him to die for the world to really call him a legend/great for his music again, and not just judge him for his personal life.

I think the same will happen with Madonna. Once the king and queen of pop are gone, it'll pave way for the Britney's, Gaga's, Justin's etc to emerge as the leading figures and it's a repeated process.
