The album is out tomorrow worldwide.
I am currently listening to it and as a big Janet fan, I was surprised about "Shoulda Known Better", which sounds like a Max Martin song but it's a Jimmy Jam + Terry Lewis one.
It has a big chorus, heys and well crafted production...
I found this, which is like an eargasm: Janet, Jam & Lewis: Deconstructing 30 Years of Music

I don't know how the guy got the official stems and other stuff to layer the stuff and I'm crying while I listen to this.
