Broadway shows made up of pop songs seem to be getting more popular. “The rise of the jukebox musical comes at a time when Broadway producers seem increasingly unable to consistently strike gold with either overtly campy new work (“Taboo,” “Bombay Dreams”), high-minded, chamber-opera fare (“Caroline, or Change”) or movie-inspired shows (“Never Gonna Dance,” “Footloose”). Add to that the near-complete inability of contemporary Broadway songs to crack the Top 40 list, and the appeal of the jukebox musical becomes even more apparent: here, it seems, is a prepackaged score guaranteed to be hummable and requiring no expensive stars.”
