This one is popsy, musical, inspiring, and more apolitical than I would have thought possible.
It's positive: "Yes We Can" is the theme (from a speech that I didn't see), and there are even positive words about Hillary Clinton in the series of short testimonials that follows the song.
And it's gloriously vague exactly what "change" means.
