In this mini-episode of Hit Parade, host Chris Molanphy is joined by Rich Juzwiak, writer for Jezebel as well as Slate’s advice column How to Do It. The two discuss the most recent full-length episode of Hit Parade, a breakdown of how Mariah Carey’s seasonal hit “All I Want for Christmas Is You” finally hit No.1 on Billboard’s Hot 100, an improbable 25 years after its original release. Rich walks Chris through the history of Mariah fandom—both his own and her loyal “Lambs”—and how he appreciates her for her low moments as much as her pop peaks. Chris quizzes a Slate Plus listener with some music trivia, and the contestant turns the tables with a chance to try to stump Chris with a question of his own. Then, Chris teases the upcoming full-length episode of Hit Parade, which will look at the history of novelty and comedy hits on the charts.  While this episode is available to all listeners, our trivia round is open only to Slate Plus members.
