I hate to insert myself into such an abysmal argument, but I believe that Janet's demographic has expanded itself slightly. I mean with all the festivals, the social media viral video and the Daddy Yankee feature (that Latin market is something serious)....she had to have gained some new fans and revived some fairweather ones.
I mean I could be wrong but wouldn't that render it impossible to know her demographic as of now? We haven't seen her promote this heavy since 20YO and she was battling a Network so she had to go hard in the paint. It would be in Janet's best interest to make this more calculated vs. just putting an album out now because it's not going to sell anyway. We know she won't do Adele numbers or Drake numbers but if she can do more than her last album...that's a win.
