One week closer to Christmas, one more week of holiday-inspired videos. While Mariah Carey covers are always appreciated—superfestive or not—there was also a lot to enjoy from some of our Artists of the Year selections, Taylor Swift, Beyoncé and Justin Bieber included. Catch up on their busy weeks, while enjoying some hip-hop inspired filmmaking and shirtless dancing from the latest viral stars below.

TAYLOR SWIFT DOES NOT ADJUST WELL TO OFFICE LIFE IN "OURS"

Of course a coworker’s playing Solitaire on the computer screen. Of course the rest of her coworkers treat the office like a personal video-gaming / paper airplane-tossing playground when they’re not lost in office malaise. Life is hard when you’re Taylor Swift stranded in real-world drudgery. Thank goodness for Matt Saracen.

JUSTIN BIEBER TRIES TO GUILT SANTA CLAUS INTO COMING TO TOWN WITH HIS SAD FACE

Elf Bieber opens the door to his creepy workshop home for the Steampunk Christmas Edition of his “Santa Claus Is Coming To Town” video.

WATCH THE THRONE: THE INDIE MOVIE

The grandiosity of the biggest rap album of the year is reduced to a kitchen scene between three female twenty-somethings. The three-minute mini-movie is constructed solely of lyrics from that album, structured to resemble a conversation between three female twenty-something roommates about partying and general lifestyle discrepancies. That shit cray, indeed.

CHRISTMAS ON THE HIGH SEAS WITH MARIAH CAREY LIP SYNCHING

This Mimi-approved lip dub pulls at our holiday heart strings. The crew certainly seem overjoyed about their homecoming in the video, which includes dancing, cross-dressing, a whole lot of shirtlessness and even a classic spelling-things-out-with-peoples’-bodies closing.

SERENA WILLIAMS TAKES YOU THERE WITH MADONNA KARAOKE PERFORMANCE

Gracing the crowd with a performance of Madonna’s “Like a Prayer," Serena broke out some seriously goofy dance moves, including what appears to be some hybrid of the Jerk and the Running Man, before the two hit the dance floor proper, occasionally getting interrupted by a hopping leprechaun.

KATIE COURIC GETS EXTRA CLOSE TO BEYONCE

Did you catch a Katie Couric holding Beyoncé's arm as they walked into Roseland Ballroom? A somewhat maternal move that strikes us as in between an act of physical support to a pregnant woman still insisting on heels, and that of an obsessed fan. We hope you checked for all of your hair after the interview, B.

MICHAEL BUBLE AND ED HELMS TEAM UP TO MAKE A CHRISTMAS HAM SANDWICH

A throwaway clip from A Michael Buble Christmas that serves to present Buble as a fun-loving, not-so-serious "passenger," as well as that crooner your mom—call it the Josh Groban effect. Cheesy Christmas sweaters? Check. Ironically bad hair (facial and otherwise)? Check, check.

NICKI MINAJ TEACHES WILLOW SMITH ABOUT FACIAL EXPRESSIONS IN "FIREBALL"

Willow leads the choreography, natch, while a rainbow mukluk-wearing Nicki Minaj shows up as her fuzzy fairy godmother, conducting lessons in facial expressions and sass, with lyrics that pay respects to her parents. It can’t hurt to stay in the good graces of Will and Jada in hopes of getting that acting career going.

DANCING WITH SHARP OBJECTS IS ACTIVELY ENCOURAGED IN NEW MAJOR LAZER VIDEO

Major Lazer’s Partysquad-directed video for “Original Don”—based on a similarly head-scratching viral-ish video entitled “Jian Sword Dancing“—features a man and a woman dancing in front of what looks to be their grandma in what looks to be their backyard, he brandishing a switchblade, she the Jian sword.

KE$HA'S NOW JUST SAYING "BEARD" OVER AND OVER AGAIN

It’s just a video Ke$ha made to advertise her beard-appreciation site in which she says the word “beard” uncountably many times, sometimes to the beat and sometimes just to amuse herself. Really, nothing we say can do justice.

Don't forget to follow all of our video coverage here. But you knew that.
