There's a difference between rushed, generic, and pure filler. Don't act like there aren't a few gems on TPP when you get past the filler. RR is run of the mill and generic all the way through.
And it was damn near a 3 year gap with TPP and RR and she started recording in 2013... so idk what your definition of "rushed" is but that's incorrect.
Not sure if you're trying to shade Nicki or whatever, but The Pinkprint is a great album that definitely wasn't rushed. She had been working on it since 2013 and it had numerous push backs.
