Long ago, there was a time when "Dark Horse" seemed like a glimmering highlight on Katy Perry's otherwise incredibly safe fourth (if you're counting 2001's past-life release Katy Hudson) album. It was the one track that didn’t just feel like a post-divorce Teenage Dream retread, all that fun-loving Katy Perry pop you love, now with more caution. But now that the non-single tracks from Prism have melted away in the consciousness of everyone but die-hard KatyKats, "Dark Horse" has superseded its album's profile, and the amount of time we've had with it has not exactly done it any favors.
"Dark Horse" is in many ways a quintessential Overplayed Song, because its repeated exposure both in airplay and in increasingly kitchen-sinked televised performances has given us far more opportunities to overthink it than it probably warrants or supports. Observing the process will change it, as will playing it every five minutes.
