Film: Mulan Best lyrics: Let's get down to business/ To defeat the Huns/ Did they send me daughters/ When I asked for sons? This is probably one of the most motivating songs that Disney have released, and regardless of your occupation and gender, it'll make you want to hit the gym and prepare yourself for war - anything to reach that flag at the top of the pole. But of course, the best thing about this song is the irony with regards to Mulan's gender. But still, her transition from a girl into a warrior is admirable.
