She is not done with the industry. She has been working on an album for 2 years now. 4 producers including Jimmy Jam have confirmed this. Even Wissam, her husband said that she is coming sooner than later. She is just taking her time with it, while at the same time trying to enjoy her life with her new husband. Her longtime friend and choreographer, Gil said she's just waiting for the right time. Just because she had some unsuccessful records doesn't mean she needs to retire. Not everything is about sales. What's wrong with just doing music because you love it and for your fans? Janet can flop for the rest of her career. She'll still be a legend and none of these newer artists will ever catch up to her so her status in this game is cemented.
She's too busy traveling and being spoiled by her billionaire husband. The life of luxury. She doesn't have to work another day in her life unless she wants too. So if she's gonna release something it has to be because she wants too not because of pressure of fans and the public.
