I’m not usually a fan of the "put learning to a song and suddenly it’s fun!" idea that seems to have infiltrated education these days, but for this I’d make an exception:
14 year old Spencer Tweedy, son of Jeff wrote this parody version of Beyoncé’s "Single Ladies" for his algebra class. The song very neatly and cleverly covers a few key math concepts like lines, slopes and digits. And it is fantastically catchy.
