Presidential politics is in the air! Hot on the heels of Super Tuesday we delve into the world of presidential campaign music. We take a trip back in time to look at how music has been used in American presidential campaigns from Washington to Obama and beyond, with lessons from the current election cycle. With Ben Sisario of the New York Times on the impact that music can have on a presidential campaign, and entertainment lawyer Joel Schoenfeld and NYU Law School Professor Christopher Sprigman on what happens when music is used without the artist's and songwriter's permission.
