AceShowbiz - Katy Perry's demo of Britney Spears' song "Passenger" has leaked online. The song which appeared on Britney's "Britney Jean" album was produced by Diplo and co-written by Katy and Sia Furler.
Lyrically, there isn't a lot of different between the demo and the finished version of "Passenger". However, Katy's version sounds less robotic and organic. It also sounds more alive, vulnerable and hopeful.
