The anger...

I think you all don't understand.
When she said that this was the last time she was going to be in her 20s when describing single releases it was for a reason.
She'll never be able to put out another version of any of the singles she's released thus far.
She secured 3 solid eras and NOW she either is going to do that dance house record or she's going to not focus on radio friendly sugary tunes but something that will be a defining moment in her career.
As long as she gives us a single by summer of 2016 then I think she's fine. Let her make her milestones 200M tours and rest and really think about how she wants to end this decade.
My guess is with a 2016 album it'll probably last until 2018 which means we wont get KP5 until the 2020s decade.
Let her go out on top on her own terms.
She's already the #1 artist of the decade and there is a sizable gap between her and what's #2.
