As the balloon drop goes on, Katy Perry's songs "Firework" and "Roar" play. And a song by Jessica Sanchez, "Stronger Together."

By comparison, one of the first songs played at the end of Donald Trump's acceptance speech at the Republican National Convention was the Rolling Stone's "You Can't Always Get What You Want."

Democratic presidential nominee Hillary Clinton speaks during the final day of the Democratic National Convention in Philadelphia, July 28, 2016.

As the balloon drop begins (!), Hillary and Bill Clinton hug on stage. Tim and Anne Kaine join them on stage as well.

Clinton ends her speech: America's destiny is ours to choose. So let's be stronger together.
