>>>My question was why was Janet sticking with a formula which obviously wasn't working?
A few possibilities.
One - she might just really be comfortable in the role. She's been playing the shy-but-you-can-find-the-sexy-person-underneath card for...what? At least a decade or so. She may simply like that groove.
Two - the genre plays to her strengths. Because, let's face it, she does not have a great singing voice. And please note - I'm not dissing her here. She's put out some great songs. "Again" kills me every time. And the reason it kills me is BECAUSE the song plays to her strengths. She sounds like a vulnerable woman who is not-quite-resigned to falling back in love with somebody she thought she was over. She's put out some good uptempo numbers, too, but most of those just display a slightly different version of the same persona. They sound vulnerable but resilient. As if to say, "You think I'm fragile, but I'm tougher than that."
But honestly, her voice isn't suited to much more. Her voice doesn't have much power. She can't belt out a number like most R&B singers. And if she's like most human beings, she's probably started losing the top part of her range, and it'll be hard for her to hit the higher notes. (Not that she exactly hits really high ones anyway.)
If I were in the producer's chair, I'd like to try out something. Get some midtempo numbers, and have her sing them in her lower register. You know - the one she uses on the first verse of "Love Will Never Do Without You". Her voice has some more "oomph" there, and that part of the range tends to stick around. It'd be interesting to see if I could get a good performance out of her sticking solely with that. Who knows - we might even get a good dance track out of it.
