The past several months have provided much fuel for political fears both at home and abroad. But there is one worrisome political development in particular that has received too little attention: Are we in danger of a protest song revival?

In May, for instance, the rapper Macklemore released “Hind’s Hall,” a song about the pro-Palestinian protests on college campuses, to surprising acclaim. Before this, Macklemore was primarily known for two things: accepting a Grammy with a particularly obsequious speech and appearing onstage in a costume that he, and virtually no one else, claimed was not antisemitic.
