If the fan speculation that Kesha has recorded something with Zedd is true, then I'm very intrigued. After hearing "Break Free", I'd be very happy for Kesha to work around that kind of production, as it's not too over-the-top and it doesn't follow the tired dance formula of verse-chorus-breakdown-verse-chorus-breakdown-chorus-chorus, but more a simpler pop music format with the breakdown saved for the end. But if she's working with Calvin Harris it'll most likely be akin to that formula, like "Summer", unless they record something more like "I Will Never Let You Down" rather than a pure dance track.
