Kesha is a talented girl, she could have pulled a Katy and gotten onto a different label and been even bigger. Or she could have been a country artist. Or she could just have been a songwriter. Or she could have been a complete flop nobody. But we'll never know.
I bet she would have been like Bonnie Mckee, writing all of Katy's hits.
I can imagine Katy singing Blow tbh
