Last Tuesday, as audience members and press were still milling about the presidential debate stage in Philadelphia after the spotlights dimmed, the real bombshell of the night dropped — Taylor Swift's endorsement Kamala Harris and Tim Walz. And this week, pop star Billie Eilish and her brother Finneas took to Instagram, announcing that they were voting for Harris and Walz.

Swift and Eilish stand amid a sea of pop stars, including, among others, Beyonce, Charli xcx, and Cardi B, who have cheered on the Harris campaign — which has felt more like a weeks-long rave than the usual pre-election slog. The soundtrack for the Democratic National Convention was provided by a sunglass-clad DJ Cassidy, while the RNC featured performances by Kid Rock and bands like Sixwire. Politics and music, this year in particular, seem inextricable. For the midweek podcast, host Brooke Gladstone speaks with Mark Clague, a professor of musicology at the University of Michigan, about the role of music in this year's presidential campaigns, the history of political anthems, and the consequences of pop star celebrity culture seeping further into our political sphere.
