Janet doesn't have to compete with Katy Perry or Lady Gaga, as they are pretty much using a diluted version of a template she mastered 20 years ago. As long as her songs have good content, anything she released will be embraced by her fans.
And what I said is that Madonna doesn't have the burden of genius. She has talent-clearly. Her ability to stay a step ahead of where everyone expects her to be is a gift.
But if she lip-syncs through her concerts, people won't really be surprised or disappointed. If she cancels a show, there is no worldwide smear campaign. She's not expected to sing the hardest pop songs anyone's recorded flawlessly 100% live. Whitney is largely considered the best vocalist anyone has every heard the last 50-60 years. She's also easily the most heavily criticized singer-even though her legacy was solidified by her ability to NAIL her songs live.
