Very true. Although we don't know everything that happened behind the scenes, there could have been things that Luke wanted Kesha to do that she didn't. Kesha's whole image of her being a party girl was arguably her and Dr. Luke's way of building star power, and it worked. At least for her first era. But Kesha didn't want to do it anymore so it came off feeling inauthentic in the end. That's just my take on it.
