Crowning the Song of the Summer has become an annual tradition akin to the Super Bowl for music pundits, spawning its own Billboard chart, a seasonal stream of speculative think pieces, and official betting odds. But no such fanfare exists for determining the Song of the Winter, an arguably more impressive achievement, given that it must seize our attention from the hectic pre-Christmas crunch through to the post-New Year’s onset of Seasonal Affective Disorder (and all the grueling family gatherings in between). Where Songs of the Summer are readymade soundtracks for the happiest moments of your life, Songs of the Winter must be scientifically engineered with enough exuberance to fire up your serotonin during the most miserable time of year. Lest we forget, some of the most universally embraced, monoculture-fortifying singles of this millennium—from "Hey Ya!" to "Crazy" to "Happy"—all surfaced during the chilly season, making their outsized energy not just welcome, but psychologically necessary. And if 2014 was indeed the hottest year on record, we can thank "Uptown Funk" for raising the mercury during its dying days.
A year ago next month, Bruno Mars appeared at the Super Bowl half-time show in a rare, shared bill with Red Hot Chili Peppers—the implication being that, even with two multi-platinum albums under his belt, the singer was somehow still too young or unproven to carry the show on his own without the help of some rock veterans. But on the heels of "Uptown Funk"—his inescapable, undeniable chart-topping collaboration with producer Mark Ronson—Mars could not only claim the show for himself this year, but make everyone in the stadium forget there was a football game going on. If "Uptown Funk" represents something of a supernova moment for Mars’ ascendant star—unleashing a braggadocio that’s several degrees sassier than what we’ve heard on his more congenially soulful solo hits—it’s a hard-fought moment of Stateside redemption for Ronson. Though his name can be found in the fine print on some of the biggest British pop records of the past decade, Ronson’s own collaboration-heavy albums failed to establish the London-born producer as a star in his own right in his second home of America (where his sister Samantha is arguably more famous for being Lindsay Lohan’s long-time party pal). His productions for others have cracked the Billboard Top 10, but this time he has a monster hit to call his own—that is, if you discount the veritable syllabus worth of '80s-funk sources "Uptown Funk" so unapologetically references. Between the Morris Day-schooled mojo and Michelle Pfeiffer name-drops, all the song is missing for maximum period detail is an Eddie Murphy cop flick to soundtrack.
