"Katy's well aware of 'Dark Horse' and we're discussing it," Thompson says. "It might be the next single. Or, due to the play it's getting now, maybe it can never have a full campaign as a single. We're watching it – and certainly appreciating the airplay – while still wanting 'Unconditionally' to have a full run."
Makes no sense, otherwise her star power would do the same for Uncle and it's not.
They should've made it the second single. Now that it's been out, making it a single after Uncle in 2014 might prove fatal. Should've jumped on it when it first blew up.
we will never see a video of this
