I Kissed A Girl was a risky lead single
Thinking Of You was a risky follow up single since it wasn't upbeat
California Gurls was a risky lead single as it was a new sound for her
E.T. was a risky follow up single as it was darker than Katy's other singles
Part Of Me was a risky reissue lead single as it had already leaked online over a year prior
Unconditionally was a risky follow up single as again it was slower, not something Katy had much success with
Dark Horse was a risky follow up single as it was a genre she never experimented with (trap)
